TOKYO (AP) — A decision by European central banks to support the region's financial system helped calm Asian markets, setting off a rally in early Friday trading.

The focus is now shifting to talks in Poland between U.S. Treasury Secretary Timothy Geithner and his European counterparts, which run through Saturday, about coordinating efforts to prevent Europe's debt crisis from derailing a global recovery.

Japan's Nikkei 225 index rose 1.7 percent to 8,819.69 while South Korea's Kospi advanced 3.5 percent to 1,835.31. Hong Kong's Hang Seng gained 2.1 percent to 19,585.10.

Worries about European banks' borrowing problems, a key element in the region's debt crisis, have been hanging over global markets in recent weeks, especially about the cash-strapped governments in Greece and Italy.

But the European Central Bank, the U.S. Federal Reserve and three other central banks said Thursday they would provide European banks with unlimited dollar loans.
