Aug 29 (Reuters) - Hungary's forint rose on Tuesday ahead of a central bank decision where it is expected to continue its 100 basis point rate cuts to revive a stagnating economy, while Chinese stocks extended gains after Beijing's policy measures over the weekend.
The forint rose 0.4% against the euro ahead of its rate decision at 1200 GMT.
The National Bank of Hungary (NBH) cut its one-day deposit rate by 100 basis points (bps) NBHK3 in May, June and July, and flagged further possible "gradual" cuts as it carries on with its easing cycle, the first in Central Europe.
"As recent market history has shown that markets can be very volatile at the end of quarters and even more so at the end of the year, the National Bank of Hungary may use this rate-setting meeting to try to anchor expectations (and market rates) for the coming year-end," said Peter Virovacz, Hungary's senior economist at ING, in a note.
Other central and eastern European currencies also rose against the euro, with the Czech crown adding 0.3%.
The Czech economy's gross domestic product on an annual basis fell by 0.4%, better than a flash estimate of a 0.6% fall.
The MSCI's index for emerging market currencies was flat at 0815 GMT, while the stocks index gained 0.8%, supported by a jump in Chinese stocks.
Hong Kong's Hang Seng index and China's blue-chip CSI 300 Index rose over 1% each, extending their rally after Beijing introduced a package of measures to boost investor confidence over the weekend, including a stamp duty cut on stock trading.
"Capital market measures like stamp duty cuts can help boost sentiment and activity," said Mark Haefele, chief investment officer at UBS Global Wealth Management.
South Africa's rand climbed 0.7% against the dollar, while the Russian rouble edged lower.
The Turkish lira fell to 26.625 against the dollar from 26.400 in the previous session.
