China bluntly criticised the United States on Saturday one day after the superpower's credit rating was downgraded, saying the "good old days" of borrowing were over.
Standard & Poor's cut the US long-term credit rating from top-tier AAA by a notch to AA-plus on Friday over concerns about the nation's budget deficits and climbing debt burden.
China -- the United States' biggest creditor -- said Washington only had itself to blame for its plight and called for a new stable global reserve currency.
"The US government has to come to terms with the painful fact that the good old days when it could just borrow its way out of messes of its own making are finally gone," China's official Xinhua news agency said in a commentary.
After a week which saw $2.5 trillion wiped off global markets, the move deepened investors' concerns of an impending recession in the United States and over the euro zone crisis.
Finance ministers and central bankers of the Group of Seven major industrialised nations will confer by telephone later on Saturday or on Sunday, a senior European diplomatic source said.
The source said the credit rating downgrade had added a global dimension on top of the euro zone debt issue, raising the need for international coordination.

French Finance Minister Francois Baroin, who would chair such a meeting under France's G7 and G20 presidency, said it was too early to say whether there would be an early G7 gathering.
In the Xinhua commentary, China condemned the United States for its "debt addiction" and "short sighted" political wrangling.
"China, the largest creditor of the world's sole superpower, has every right now to demand the United States address its structural debt problems and ensure the safety of China's dollar assets," it said.
It urged the United States to cut military and social welfare expenditure. Further credit downgrades would very likely undermine the world economic recovery and trigger new rounds of financial turmoil, it said.
"International supervision over the issue of US dollars should be introduced and a new, stable and secured global reserve currency may also be an option to avert a catastrophe caused by any single country," Xinhua said.
