                                         MORGAN STANLEY ASIA-PACIFIC FUND, INC.

LETTER TO STOCKHOLDERS
                                         Overview

PERFORMANCE

For the six months ended June 30, 2004, the Morgan Stanley Asia-Pacific Fund,
Inc. (the "Fund") had a total return, based on net asset value per share of
5.48%, compared with 4.75% for its benchmark. The benchmark for the Fund is
comprised of two Morgan Stanley Capital International (MSCI) indices; Japan Net
and All-Country Asia-Pacific Free ex-Japan Net (the "Index"), with each index
weighted equally. On June 30, 2004, the closing price of the Fund shares on the
New York Stock Exchange was $11.25, representing a 13.1% discount to the Fund's
net asset value per share.

FACTORS AFFECTING PERFORMANCE

   -  The Fund's outperformance over the six-month period was largely
      attributable to stock selection in Japan and India.

   -  Within the Japanese market, performance was supported in particular by
      stock selection and overweight positions within the materials and consumer
      durables sectors relative to the Index. These sectors performed well as
      investors shifted their focus to earnings growth potential from momentum
      and improved domestic consumer spending drove the country's economic
      recovery.

   -  Profit margins and return on assets of Japanese companies are hitting post
      bubble highs for select Japanese companies and with recent worries about
      the global economy, China's economic slowdown, interest rates and finally
      elections, investors will likely focus on companies with the highest
      quality and most visible earnings.

   -  The cyclical economy is now showing signs of permeating into the domestic
      Japanese economy and real household spending in May rose 5.6%, the highest
      growth rate in 21 years.

MANAGEMENT STRATEGIES

   -  Despite the downdraft in Asia ex-Japan, we find the economic outlook for
      the region is structurally on a sounder footing and liquidity conditions
      extremely favorable, even though the momentum of growth has certainly
      peaked.

   -  Exports into China and the U.S. continue to grow at a steady pace and
      domestic demand has stayed robust in most Asian countries except for South
      Korea.

   -  We believe the Asian economies are in much better shape than a decade ago,
      with huge current account surpluses, a healthier backing system and
      reduced external debt levels.

   -  Outside of China, investment to gross domestic product has been on a
      decline and capacity utilizations are rising; we believe that we are
      likely to see an investment pickup in many Asian countries.

   -  Over the last several months, the correlation of buying Japanese stocks
      with the movement of U.S. stocks has begun to break down, resulting in a
      view that Japan's domestic demand may grow regardless of the world trade
      environment and Japanese equities may continue to rise based on relatively
      favorable valuations and growth rate. Our view is that investors will need
      to become more selective than the past year, look to companies with cash
      assets and discriminate between liquidity driven stocks and those with
      visible earning.


Sincerely,


/s/ Ronald E. Robison

NOTES TO FINANCIAL STATEMENTS
                                         June 30, 2004 (unaudited)

     The Morgan Stanley Asia-Pacific Fund, Inc. (the "Fund") was incorporated in
Maryland on February 28, 1994, and is registered as a non-diversified,
closed-end management investment company under the Investment Company Act of
1940 (the "1940 Act"), as amended. The Fund's investment objective is long-term
capital appreciation through investments primarily in equity securities.

A. ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with accounting principles generally accepted in the United States.
Such policies are consistently followed by the Fund in the preparation of its
financial statements. Accounting principles generally accepted in the United
States may require management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results may
differ from those estimates.

1.   SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued
     at the latest quoted sales price on the valuation date. Equity securities
     listed or traded on NASDAQ, for which market quotations are available, are
     valued at the NASDAQ Official Closing Price. Securities listed on a foreign
     exchange are valued at their closing price. Unlisted securities and listed
     securities not traded on the valuation date for which market quotations are
     readily available are valued at the mean between the current bid and asked
     prices obtained from reputable brokers. Debt securities purchased with
     remaining maturities of 60 days or less are valued at amortized cost, if it
     approximates value.

     All other securities and investments for which market values are not
     readily available, including restricted securities, and those securities
     for which it is inappropriate to determine prices in accordance with the
     aforementioned procedures, are valued at fair value as determined in good
     faith under procedures adopted by the Board of Directors, although the
     actual calculations may be done by others. Factors considered in making
     this determination may include, but are not limited to, information
     obtained by contacting the issuer, analysts, or the appropriate stock
     exchange (for exchange-traded securities), analysis of the issuer's
     financial statements or other available documents and, if necessary,
     available information concerning other securities in similar circumstances.

     Most foreign markets close before the New York Stock Exchange (NYSE).
     Occasionally, developments that could affect the closing prices of
     securities and other assets may occur between the times at which valuations
     of such securities are determined (that is, close of the foreign market on
     which the securities trade) and the close of business on the NYSE. If these
     developments are expected to materially affect the value of the securities,
     the valuations may be adjusted to reflect the estimated fair value as of
     the close of the NYSE, as determined in good faith under procedures
     established by the Board of Directors.

2.   REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements under
     which the Fund lends excess cash and takes possession of securities with an
     agreement that the counterparty will repurchase such securities. In
     connection with transactions in repurchase agreements, a bank as custodian
     for the Fund takes possession of the underlying securities (collateral),
     with a market value at least equal to the amount of the repurchase
     transaction, including principal and accrued interest. To the extent that
     any repurchase transaction exceeds one business day, the value of the
     collateral is marked-to-market on a daily basis to determine the adequacy
     of the collateral. In the event of default on the obligation to repurchase,
     the Fund has the right to liquidate the collateral and apply the proceeds
     in satisfaction of the obligation. In the event of default or bankruptcy by
     the counterparty to the agreement, realization and/or retention of the
     collateral or proceeds may be subject to legal proceedings.

     The Fund, along with other affiliated investment companies, may utilize a
     joint trading account for the purpose of entering into one or more
     repurchase agreements.

3.   FOREIGN CURRENCY TRANSLATION: The books and records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars at the mean of the bid and asked prices of such currencies
     against U.S. dollars last quoted by a major bank as follows:

     -  investments, other assets and liabilities at the prevailing rates of
        exchange on the valuation date;

     -  investment transactions and investment income at the prevailing rates of
        exchange on the dates of such transactions.

     Although the net assets of the Fund are presented at the foreign exchange
     rates and market values at the close of the period, the Fund does not
     isolate that portion of the results of operations arising as a result of
     changes in the

NOTES TO FINANCIAL STATEMENTS (CONT'D)
                                         June 30, 2004 (unaudited)

     foreign exchange rates from the fluctuations arising from changes in the
     market prices of the securities held at period end. Similarly, the Fund
     does not isolate the effect of changes in foreign exchange rates from the
     fluctuations arising from changes in the market prices of securities sold
     during the period. Accordingly, realized and unrealized foreign currency
     gains (losses) due to securities transactions are included in the reported
     net realized and unrealized gains (losses) on investment transactions and
     balances.

     Net realized gains (losses) on foreign currency transactions represent net
     foreign exchange gains (losses) from sales and maturities of foreign
     currency exchange contracts, disposition of foreign currencies, currency
     gains or losses realized between the trade and settlement dates on
     securities transactions, and the difference between the amount of
     investment income and foreign withholding taxes recorded on the Fund's
     books and the U.S. dollar equivalent amounts actually received or paid. Net
     unrealized currency gains (losses) from valuing foreign currency
     denominated assets and liabilities at period end exchange rates are
     reflected as a component of unrealized appreciation (depreciation) on
     investments and foreign currency translations in the Statement of Net
     Assets. The change in net unrealized currency gains (losses) on foreign
     currency translations for the period is reflected in the Statement of
     Operations.

     A significant portion of the Fund's net assets consist of securities of
     issuers located in Asia which are denominated in foreign currencies.
     Changes in currency exchange rates will affect the value of and investment
     income from such securities. Asian securities are subject to greater price
     volatility, limited capitalization and liquidity, and higher rates of
     inflation than securities of companies based in the United States. In
     addition, Asian securities may be subject to substantial governmental
     involvement in the economy and greater social, economic and political
     uncertainty. Such securities may be concentrated in a limited number of
     countries and regions and may vary throughout the year.

The Fund may use derivatives to achieve its investment objectives. The Fund may
engage in transactions in futures contracts on foreign currencies, stock
indices, as well as in options, swaps and structured notes. Consistent with the
Fund's investment objectives and policies, the Fund may use derivatives for
non-hedging as well as hedging purposes.

Following is a description of derivative instruments that the Fund has utilized
and their associated risks:

4.   FOREIGN CURRENCY EXCHANGE CONTRACTS: The Fund may enter into foreign
     currency exchange contracts to attempt to protect securities and related
     receivables and payables against changes in future foreign exchange rates
     and, in certain situations, to gain exposure to a foreign currency. A
     foreign currency exchange contract is an agreement between two parties to
     buy or sell currency at a set price on a future date. The market value of
     the contract will fluctuate with changes in currency exchange rates. The
     contract is marked-to-market daily and the change in market value is
     recorded by the Fund as unrealized gain or loss. The Fund records realized
     gains or losses when the contract is closed equal to the difference between
     the value of the contract at the time it was opened and the value at the
     time it was closed. Risk may arise upon entering into these contracts from
     the potential inability of counterparties to meet the terms of their
     contracts and is generally limited to the amount of unrealized gain on the
     contracts, if any, at the date of default. Risks may also arise from
     unanticipated movements in the value of a foreign currency relative to the
     U.S. dollar.

5.   STRUCTURED SECURITIES: The Fund may invest in interests in entities
     organized and operated solely for the purpose of restructuring the
     investment characteristics of sovereign debt obligations. This type of
     restructuring involves the deposit with or purchase by an entity of
     specified instruments and the issuance by that entity of one or more
     classes of securities ("Structured Securities") backed by, or representing
     interests in, the underlying instruments. Structured Securities generally
     will expose the Fund to credit risks of the underlying instruments as well
     as of the issuer of the Structured Security. Structured Securities are
     typically sold in private placement transactions with no active trading
     market. Investments in Structured Securities may be more volatile than
     their underlying instruments, however, any loss is limited to the amount of
     the original investment.

6.   OVER-THE-COUNTER TRADING: Securities and other derivative instruments that
     may be purchased or sold by the Fund may consist of instruments not traded
     on an exchange. The risk of nonperformance by the obligor on such an
     instrument may be greater, and the ease with which the Fund can dispose of
     or enter into closing transactions with respect to such an instrument may

     case of an exchange-traded instrument. In addition, significant disparities
     may exist between bid and asked prices for derivative instruments that are
     not traded on an exchange. Derivative instruments not traded on exchanges
     are also not subject to the same type of government regulation as exchange
     traded instruments, and many of the protections afforded to participants in
     a regulated environment may not be available in connection with such
     transactions.

7.   OTHER: Security transactions are accounted for on the date the securities
     are purchased or sold. Investments in new Indian securities are made by
     making applications in the public offerings. The issue price, or a portion
     thereof, is paid at the time of application and is reflected as share
     application money on the Statement of Net Assets, if any. Upon allotment of
     the securities, this amount plus any remaining amount of issue price is
     recorded as cost of investments. Realized gains and losses on the sale of
     investment securities are determined on the specific identified cost basis.
     Interest income is recognized on the accrual basis. Dividend income is
     recorded on the ex-dividend date (except certain dividends which may be
     recorded as soon as the Fund is informed of such dividends) net of
     applicable withholding taxes. Distributions to stockholders are recorded on
     the ex-dividend date.

B. ADVISER: Morgan Stanley Investment Management Inc. (the "Adviser") provides
investment advisory services to the Fund under the terms of an Investment
Advisory and Management Agreement (the "Agreement"). Under the Agreement, the
Adviser is paid a fee computed weekly and payable monthly at an annual rate of
1.00% of the Fund's average weekly net assets.

C. ADMINISTRATOR: JPMorgan Chase & Co., through its corporate affiliate J.P.
Morgan Investor Services Co. (the "Administrator"), provides administrative
services to the Fund under an Administration Agreement. The Administrator is
paid a fee computed weekly and payable monthly at an annual rate of 0.02435% of
the Fund's average weekly net assets, plus $24,000 per annum. In addition, the
Fund is charged for certain out-of-pocket expenses incurred by the Administrator
on its behalf. An employee of the Administrator is an Officer of the Fund.

D. CUSTODIAN: JPMorgan Chase Bank and its affiliates serve as custodian for the
Fund. The Custodian holds cash, securities, and other assets of the Fund as
required by the 1940 Act. Custody fees are payable monthly based on assets held
in custody, investment purchase and sales activity and account maintenance fees,
plus reimbursement for certain out-of-pocket expenses.

E. FEDERAL INCOME TAXES: It is the Fund's intention to continue to qualify as a
regulated investment company and distribute all of its taxable income.
Accordingly, no provision for Federal income taxes is required in the financial
statements. Dividend income and distributions to stockholders are recorded on
the ex-dividend date.

The Fund may be subject to taxes imposed by countries in which it invests. Such
taxes are generally based on income and/ or capital gains earned or repatriated.
Taxes are accrued and applied to net investment income, net realized gains and
net unrealized appreciation as such income and/or gains are earned.

The tax character of distributions paid may differ from the character of
distributions shown on the Statements of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. The tax
character of distributions paid during 2003 and 2002 was as follows:



      2003 DISTRIBUTIONS               2002 DISTRIBUTIONS
          PAID FROM:                       PAID FROM:
            (000)                            (000)
------------------------------   ------------------------------
                     LONG-TERM                    LONG-TERM
         ORDINARY      CAPITAL      ORDINARY        CAPITAL
           INCOME         GAIN        INCOME           GAIN
---------------------------------------------------------------
                                               
           $3,175          $--          $277            $--


The amount and character of income and capital gain distributions to be paid by
the Fund are determined in accordance with Federal income tax regulations, which
may differ from accounting principles generally accepted in the United States.
The book/tax differences are considered either temporary or permanent in nature.

Temporary differences are attributable to differing book and tax treatments for
the timing of the recognition of gains and losses on certain investment
transactions and the timing of the deductibility of certain expenses.

Permanent book and tax basis differences may result in reclassifications among
undistributed (distributions in excess of) net investment income (or accumulated
net investment loss), accumulated net realized gain (loss) and paid-in capital.

NOTES TO FINANCIAL STATEMENTS (CONT'D)
                                         June 30, 2004 (unaudited)

At December 31, 2003, the components of distributable earnings on a tax basis
were as follows:



       UNDISTRIBUTED         UNDISTRIBUTED
      ORDINARY INCOME    LONG-TERM CAPITAL GAIN
           (000)                 (000)
-----------------------------------------------------
                               
           $431                   $--
-----------------------------------------------------


At June 30, 2004, the U.S. Federal income tax cost basis of investments was
approximately $401,312,000 and, accordingly, net unrealized appreciation for
U.S. Federal income tax purposes was $60,538,000 of which $98,761,000 related to
appreciated securities and $38,223,000 related to depreciated securities.

At December 31, 2003, the Fund had a capital loss carryforward for U.S. Federal
income tax purposes of approximately $205,795,000 available to offset future
capital gains, of which $128,632,000 will expire on December 31, 2006,
$73,333,000 will expire on December 31, 2009 and $3,830,000 will expire on
December 31, 2010.

To the extent that capital loss carryovers are used to offset any future capital
gains realized during the carryover period as provided by U.S. Federal income
tax regulations, no capital gains tax liability will be incurred by the Fund for
gains realized and not distributed. To the extent that capital gains are offset,
such gains will not be distributed to the stockholders.

Net capital and currency losses incurred after October 31, and within the
taxable year are deemed to arise on the first business day of the Fund's next
taxable year. For the year ended December 31, 2003, the Fund did not defer any
post-October losses to January 1, 2004, for U.S. Federal income tax purposes.

F. CONTRACTUAL OBLIGATIONS: The Fund enters into contracts that contain a
variety of indemnifications. The Fund's maximum exposure under these
arrangements is unknown. However, the Fund has not had prior claims or losses
pursuant to these contracts and expects the risk of loss to be remote.

G. OTHER: During the six months ended June 30, 2004, the Fund made purchases and
sales totaling approximately $65,266,000 and $68,130,000 respectively, of
investment securities other than long-term U.S. Government securities, purchased
options and short-term investments. There were no purchases or sales of
long-term U.S. Government securities.

During the six months ended June 30, 2004, the Fund incurred a combined total of
$33,600 in brokerage commissions paid to affiliated broker dealers, of which
$32,500 was paid to Morgan Stanley & Co. Incorporated and $1,100 was paid to
China International Capital Corporation.

On January 23, 1998, the Fund commenced a share repurchase program for purposes
of enhancing stockholder value and reducing the discount at which the Fund's
shares trade from their net asset value. For the six months ended June 30, 2004,
the Fund repurchased 48,614 of its shares at an average discount of 15.97% from
net asset value per share. Since the inception of the program, the Fund has
repurchased 15,192,619 of its shares at an average discount of 20.48% from net
asset value per share. The Fund expects to continue to repurchase its
outstanding shares at such time and in such amounts as it believes will further
the accomplishment of the foregoing objectives, subject to review by the Board
of Directors.

On June 21, 2004 the Officers of the Fund, pursuant to authority granted by the
Board of Directors declared a distribution of $0.0121 per share, derived from
net investment income, payable on July 15, 2004, to stockholders of record on
June 30, 2004.

                                         MORGAN STANLEY ASIA-PACIFIC FUND, INC.

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

     Pursuant to the Dividend Reinvestment and Cash Purchase Plan (the "Plan"),
each stockholder will be deemed to have elected, unless American Stock Transfer
& Trust Company (the "Plan Agent") is otherwise instructed by the stockholder in
writing, to have all distributions automatically reinvested in Fund shares.
Participants in the Plan have the option of making additional voluntary cash
payments to the Plan Agent, annually, in any amount from $100 to $3,000, for
investment in Fund shares.

     Dividend and capital gain distributions will be reinvested on the
reinvestment date in full and fractional shares. If the market price per share
equals or exceeds net asset value per share on the reinvestment date, the Fund
will issue shares to participants at net asset value. If net asset value is less
than 95% of the market price on the reinvestment date, shares will be issued at
95% of the market price. If net asset value exceeds the market price on the
reinvestment date, participants will receive shares valued at market price. The
Fund may purchase shares of its Common Stock in the open market in connection
with dividend reinvestment requirements at the discretion of the Board of
Directors. Should the Fund declare a dividend or capital gain distribution
payable only in cash, the Plan Agent will purchase Fund shares for participants
in the open market as agent for the participants.

     The Plan Agent's fees for the reinvestment of dividends and distributions
will be paid by the Fund. However, each participant's account will be charged a
pro rata share of brokerage commissions incurred on any open market purchases
effected on such participant's behalf. A participant will also pay brokerage
commissions incurred on purchases made by voluntary cash payments. Although
stockholders in the Plan may receive no cash distributions, participation in the
Plan will not relieve participants of any income tax which may be payable on
such dividends or distributions.

     In the case of stockholders, such as banks, brokers or nominees, that hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
stockholder as representing the total amount registered in the stockholder's
name and held for the account of beneficial owners who are participating in the
Plan.

     Stockholders who do not wish to have distributions automatically reinvested
should notify the Plan Agent in writing. There is no penalty for
non-participation or withdrawal from the Plan, and stockholders who have
previously withdrawn from the Plan may rejoin at any time. Requests for
additional information or any correspondence concerning the Plan should be
directed to the Plan Agent at:
