Chinese President Xi Jinping and his U.S. counterpart Barrack Obama have agreed during their meeting the two sides will maintain close communication and coordination on regional hotshot issues, Chinese State Councilor Yang Jiechi said Saturday.

During his talks with Obama, Xi reaffirmed China's persistence in keeping peace and stability on the Korean Peninsular and in realizing denuclearization there.

China adheres to the principle that the issue be solved through dialogue and consultation and it will continue to make unremitting efforts toward a solution, Xi said.

The respective stance and overall objective by China and the United States in this regard are in accord, the Chinese president said, adding that China is willing to maintain close communication and cooperation with the U.S. side over the issue.

Xi also expounded on China's stance on Diaoyu Islands and the South China Sea. He reaffirmed that China is determined to safeguard national sovereignty and territorial integrity while adhering to solving relevant issues through dialogue.

He urged relevant parties to adopt a responsible attitude, stop provocation and return to talks as early as possible so as to properly solve the issues.

The two leaders also agreed to support regional economic integration in the Asia-Pacific, to promote regional connectivity, and to enhance cooperation in multilateral regional frameworks, Yang said.

The Xi-Obama summit and the preceding three-nation tour in Latin America have shown that China is committed to the promotion of trans-Pacific cooperation, said Yang, who previously served as China's foreign minister.

"The summit meeting and the visits also demonstrate China's willingness to work jointly with countries within or beyond the Asia-Pacific region to maintain peace and stability and promote common development in the region, " Yang added.

Xi left California for home Saturday afternoon after his meeting with Obama. Before his U.S. trip, Xi visited Trinidad and Tobago, Costa Rica and Mexico. Endi
