Russia’s new president, Dmitri A. Medvedev, less swaggering than his predecessor but as touchy about criticism from abroad, said in an interview that an America in “essentially a depression” was in no position to lecture other countries on how to conduct their affairs. ...

In the interview, Mr. Medvedev was asked about a call by Senator John McCain of Arizona, the presumptive Republican presidential nominee, to bar Russia from the Group of 8 because of its record on democracy. ...

“The Group of 8 exists not because someone likes or dislikes it, but because objectively, they are the biggest world economies and the most serious players from the foreign policy point of view,” Mr. Medvedev said. “Any attempts to put restrictions on anyone in this capacity will damage the entire world order.”

He added, “I am sure that any administration of the United States of America, if it wishes to succeed, among other things, in overcoming essentially a depression that exists in the American economic market, must conduct a pragmatic policy inside the country and abroad.”

Mr. Medvedev said world leaders should realize that the credit crunch and a gathering global recession signaled that the worldwide economic architecture needed to be overhauled. He did not specify how this should be done, but indicated it should entail a reduction in the influence of the United States.

“It has to be improved, it has to be more up-to-date, better protected from risks, and it must not suffer from national egoism, financial and economic egoism, but must be more fair toward other countries; this is absolutely evident,” he said. “This system cannot be oriented toward only one country and only one currency.”
