Japanese Finance Minister Jun Azumi, after meetings with Chinese Vice Premier Wang Qishan and Finance Minister Xie Xuren, said the two countries were ready to support the IMF but further efforts by euro zonemembers were necessary.
"What we agreed on...is that European countries need to do more, although (the situation), including Greece, is headed in a good direction," Azumi told reporters in Beijing.
"We can expect some sort of request from the IMF to those including the United States, Japan and China. We agreed that Japan and China will coordinate closely and will jointly respond to IMF."
The IMF is seeking to raise $600 billion in new resources to help deal wit the euro zone debt crisis but countries outside of the 17-country euro bloc want to see its members stump up more money before they commit additional resources to the IMF.
Azumi said the two sides did not discuss the specific size of any funding support for the IMF although a Japanese finance ministry official said Tokyo was willing to commit a "sizeable" amount.
"The idea is Japan and China will coordinate, not compete, on any IMF action," the official said, adding that both countries were fully aware of their importance in dealing with the crisis.
China, which has been consistently reluctant to make firm financial commitments, is seen as having the financial firepower to bail out some European governments given its $3.2 trillion worth foreign exchange reserves at hand.
Earlier in the month, Chinese Premier Wen Jiabao said the world's No. 2 economy is considering increasing its participation in the European rescue funds and is still studying how it might go about doing it, including possibly through the IMF.
MORE FLEXIBLE YUAN
China's official Xinhua news agency quoted Vice Premier Wang Qishan as telling Azumi that China and Japan must "proactively study" local currency settlement for trade and investment and should further enhance financial coordination.
China has become Japan's biggest export destination and No.1 trading partner, taking over from the United States. Trade between the two countries expanded 14 percent to a record high $344.91 billion in 2011, boosted by a rise in Chinese exports to this neighbor, according to the Japan External Trade Organization said.
However, the bulk of trade between the world's second-largest and third-largest economies is currently settled in dollars, due in large part to financial regulations and market custom.
As part of efforts to promote direct exchanges of the yen and the yuan, which would lower currency risks and settlement costs, Japan hopes to eventually set up an offshore yuan settlement centre in Tokyo, joining other countries including Britain and Singapore that are seeking a share of the growing offshore yuan business.
Azumi said he told the Chinese side: "If the yen and yuan are to be settled directly, a more flexible and an international yuan will be needed."
"Since China is a major player in the global economy, I hope China will take that into consideration and be more flexible (in its currency policy)."
