(Reuters) - Vice President Joe Biden said on Tuesday the United States would overcome its debt crisis and Japan would move on from its devastating earthquake in March, warning doubters not to count the two countries out.
Biden, who kicked off a trip to Asia last week with talks in Beijing, met Japanese Prime Minister Naoto Kan in Tokyo to discuss rebuilding efforts after the March 13 earthquake and tsunami which killed more than 20,000 people and triggered the world's biggest nuclear disaster since Chernobyl in 1986.
In opening remarks, Biden said he had come to Japan to express U.S. sympathy and admiration for Japan's handling of the earthquake and he made a robust case that neither Japan nor the United States was in decline.
"While you're struggling to deal with one of the greatest natural disasters any country has faced and we are dealing with getting our budget in order, there are voices in the world who are counting us out," Biden said.
"They're making a very bad bet."
Kan thanked Biden for the "enormous assistance" the United States had provided to Japan and said his visit was a positive signal.
"We are back in business," Kan said, according to a translator. "This visit ... demonstrates to the world that Japan is open for business."
Unpopular Kan will likely resign at the end of this month, his economics minister said on Tuesday, setting the stage for parliament to pick Japan's sixth leader in five years as the country confronts the nuclear crisis and economic woes of its own.
Japanese ties with Washington frayed after the Democratic Party took office in 2009 and then-Prime Minister Yukio Hatoyama sought to keep a campaign pledge to move the U.S. Marines' Futenma air base off its southern island of Okinawa.
Japan last year agreed with the United States to stick to a 2006 deal to move the base to a less populous area on the island, but the Japanese government has yet to win support for that plan from local residents.
Tomoaki Iwai, political science professor at Nihon University, said the earthquake and political turmoil meant Japan's diplomacy has been non-existent.
"The United States extended great help with its Operation "Tomodachi" (earthquake rescue and relief). So the Japanese side is thankful to the United States," he said.
"But no progress has been made on the Futenma issue and decision... Japan and the United States remain on good terms, but they have been in a situation where nothing moves forward."
Referring to his talks in Beijing, Biden said on Monday China's leaders had not sought reassurances about the weak U.S. economy, and he called Xi Jinping -- the man expected to take over as China's next president -- pragmatic and strong.
Many analysts viewed Biden's trip as a tour to convince China, the largest foreign holder of U.S. debt, that its investments are safe after a bitter political debate in Washington over U.S. debt and deficit problems sparked a credit downgrade.
Biden said one of the main purposes of his trip to China was to emphasize that the United States was a Pacific power, like Japan.
"We are a Pacific power. You are a Pacific power. You are our ally, both in your power economically and politically, (which) is something that we value a great deal."
