As the world is concerned about the catastrophe in Japan, the mega-disaster may also bring about a diplomatic opening as the United States and neighbors reach out to the newly vulnerable nation, said an article by Agence France-Presse on March 15.

Although relations with Japan have been strained over military issues, the article said, the United States has launched a wide-scale relief effort.

South Korea, with memories of Japanese colonial rule still vivid, has poured sympathy and provided assistance for quake victims, said the article.

The article also pointed out that China and Russia, which both have experienced rocky relations with Japan, offered help. While Russia sent rescue teams to Japan and pledged energy to make up shortfalls, Chinese Premier Wen Jiabao offered any assistance needed.

Even North Korea, Japan's arch-enemy, carried a rare condolence message in its state media to the Japanese Red Cross Society, said the article.

"I think the image of Japan may have changed in the eyes of its regional neighbors. It is no longer all-powerful Japan, but a country that really needs their help," said Weston Konishi, an Asia expert at the Institute for Foreign Policy Analysis. "I think there is genuine sympathy, and I think that can play into a thawing of diplomatic relations and perhaps lead to more reconciled dynamics."
