Chinese Vice President Xi Jinping met U.S. President Barack Obama at the White House in Washington DC on Tuesday morning, and handed him a letter written by Chinese President Hu Jintao.

Hu reiterated in the letter that he would like to promote the China-U.S. cooperative partnership based on mutual respect and mutual benefit, and tackle with the challenges with Obama together.

Xi said on Tuesday that the purpose of his visit is to promote the China-U.S. relationship in accordance with the important consensus reached by President Hu Jintao and President Obama.

Obama said it's vital for the U.S. to have strong relations with China and his country welcomes the peaceful rise of China.

"I have always emphasized that we welcome China's peaceful rise, that we believe that a strong and prosperous China is one that can help to bring stability and prosperity to the region and to the world," Obama said.

"And we expect to be able to continue on the cooperative track that we've tried to establish over the last three years," he added, recalling that over the last three years he has had "a great opportunity to develop a strong working relationship" with Chinese President Hu Jintao.

"We have continually tried to move forward on the basis of recognizing that a cooperative relationship based on mutual interest and mutual respect is not only in the interests of the United States and China, but is also in the interest of the region and... in the interest of the world," he noted.
