With the shadow of the U.S. debt crisis and unease about arms sales to Taiwan, Biden is visiting China from Wednesday to next Monday.

Biden arrived at Beijing International Airport Wednesday Evening.

Later, he is to meet with Chinese Vice President Xi Jinping and top legislator Wu Bangguo.

During the visit, Biden will also stop in Chengdu, capital city of southwest China's Sichuan Province, where he will deliver a keynote speech at Sichuan University.

The trip is his first to China since he took office in 2009.

It comes after the U.S.'s loss of its top-tier triple A credit rating from Standard & Poor's.

The White House says Biden's trip aims to boost Chinese investors' confidence in the U.S. economy, as China is currently the U.S.' largest holder of its debt.

Meanwhile, monetary policy is one of the biggest issues in China-U.S. relations. The U.S. alleges the yuan is undervalued, and has been pushing China to appreciate the currency.

U.S. arms sales to Taiwan have also been an issue between the two countries for many years.

As the 2012 general election approaches, some U.S. lawmakers have started pressuring the Obama administration to sell F-16 fighter jets to Taiwan, at a cost of $4.5 billion. U.S. media suggests Washington will announce its decision in September.

However, White House officials say it is not top of U.S. Vice President Joe Biden's agenda.

His visit to China is part of a trip that will also take him to Mongolia and Japan.
