discounts is available from your financial professional and in the Shareholder

Example

The Example is intended to help you compare the cost of investing in the fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the fund for the time periods indicated and then redeem all
of your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

Expense Example Dreyfus Emerging Markets Fund (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
Class A	745	1,103	1,484	2,549
Class B	681	1,162	1,669	2,649
Class C	359	796	1,360	2,895
Class I	160	496	855	1,867

You would pay the following expenses if you did not redeem your shares:

Expense Example, No Redemption Dreyfus Emerging Markets Fund (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Class A	745	1,103	1,484	2,549
Class B	281	862	1,469	2,649
Class C	259	796	1,360	2,895
Class I	160	496	855	1,867

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover may
indicate higher transaction costs and may result in higher taxes when fund
shares are held in a taxable account. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the fund's performance.
During the most recent fiscal year, the fund's portfolio turnover rate was
68.19% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its net assets,
plus any borrowings for investment purposes, in the stocks of companies
organized, or with a majority of assets or business, in emerging market
countries. In selecting stocks, the portfolio managers identify potential
investments through extensive quantitative and fundamental research using a
value-oriented, research-driven approach. Emphasizing individual stock selection
rather than economic and industry trends, the fund focuses on value, business
health and business momentum.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed
by the Federal Deposit Insurance Corporation (FDIC) or any other government
agency. It is not a complete investment program. The fund's share price
fluctuates, sometimes dramatically, which means you could lose money.

o Foreign investment risk. Investments in foreign securities carry additional
risks, including exposure to currency fluctuations, less liquidity, less
developed or efficient trading markets, lack of comprehensive company
information, political instability and differing auditing and legal standards.
To the extent the fund's investments are concentrated in a limited number of
foreign countries, the fund's performance could be more volatile than that of
more geographically diversified funds.

o Emerging market risk. The securities of issuers located in emerging markets
tend to be more volatile and less liquid than securities of issuers located in
more mature economies, and emerging markets generally have less diverse and less
mature economic structures and less stable political systems than those of
developed countries. The securities of issuers located or doing substantial
business in emerging markets are often subject to rapid and large changes in
price.

o Foreign currency risk. Investments in foreign currencies are subject to the
risk that those currencies will decline in value relative to the U.S. dollar,
which will reduce the value of investments denominated in those currencies held
by the fund.

o Risks of stock investing. Stocks generally fluctuate more in value than bonds
and may decline significantly over short time periods. There is the chance that
stock prices overall will decline because stock markets tend to move in cycles,
with periods of rising prices and falling prices. The market value of a stock
may decline due to general weakness in the stock market or because of factors
that affect the company or its particular industry.

o Non-diversification risk. The fund is non-diversified, which means that the
fund may invest a relatively high percentage of its assets in a limited number
of issuers. Therefore, the fund's performance may be more vulnerable to changes
in the market value of a single issuer or group of issuers and more susceptible
to risks associated with a single economic, political or regulatory occurrence
than a diversified fund.

Performance

The following bar chart and table provide some indication of the risks of
investing in the fund. The table compares the average annual total returns
of the fund's shares to those of a broad measure of market performance.
The fund's past performance (before and after taxes) is no guarantee of
future results. More recent performance information may be available at
www.dreyfus.com.

The bar chart shows changes in the performance of the fund's Class A shares
from year to year. Sales charges, if any, are not reflected in the bar chart,
and if those charges were included, returns would have been less than those
shown.

Year-by-Year Total Returns as of 12/31 each year (%) Class A

Best Quarter
Q2, 2009: 36.58%
Worst Quarter
Q4, 2008: -25.48%

The year-to-date total return of the fund's Class A shares as of 6/30/11 was
-2.52%.

After-tax performance is shown only for Class A shares. After-tax performance of
the fund's other share classes will vary. After-tax returns are calculated using
the historical highest individual federal marginal tax rates, and do not reflect
the impact of state and local taxes. Actual after-tax returns depend on the
investor's tax situation and may differ from those shown, and the after-tax
returns shown are not relevant to investors who hold their shares through
tax-deferred arrangements such as 401(k) plans or individual retirement
accounts.

The performance figures for the fund's Class B, C and I shares for periods prior
to 11/15/02 reflect the performance of the fund's Class A shares adjusted to
reflect each share class' applicable sales charge. Such performance figures have
not been adjusted, however, to reflect applicable class fees and expenses; if
such fees and expenses had been reflected, the performance shown for Class B and
C shares for such periods may have been lower.
