Vice President Biden is in Tokyo, starting a week-long trip to Japan, China, and South Korea.

In addition to U.S. relations with Asia, Biden will also work with the three nations on disputes they're having with each other.

After landing Monday in Japan, Biden was greeted by new U.S. ambassador Caroline Kennedy.

The Associated Press outlines Biden's trip:

"While in Japan, Biden will meet with Prime Minister Shinzo Abe. He'll also tour a technology company and highlight women's role in Japan's economy.

"Later in the week, Biden will meet in China with President Xi Jinping amid an international spat over China's new air defense zone.

"Biden will wrap up the trip in Seoul, where he'll meet with South Korea's president and prime minister. He'll deliver a speech about U.S.-Korean relations and be briefed on the North Korean nuclear situation."
