In a sign that Athens is keen to seek a new deal, Greece's combative finance minister, Yanis Varoufakis, resigned on Monday, apparently under pressure from other euro zone finance ministers who did not want him as a negotiating partner.

Asian assets were also increasingly burdened by rising concerns over massive losses in Chinese stock markets over the past month or so.

"Prior to the selloff the Chinese market looked bubbly, kept rising even as the economy is slowing. It will take some time for the market to calm down," said Shuji Shirota, head of macroeconomics strategy group at HSBC in Tokyo.
"Judging from Japanese experience it is not easy to support share prices just by price keeping operation," he said, referring to Japanese attempts in the 1990s to shore up the stock market by using public funds to buy shares.
Fears of instability in the Chinese economy dented many types of assets that are thought to be leveraged to demand from China.
