Joint efforts needed to improve world order

With President Xi Jinping's state visit to the United States coming to an end, many observers are trying to fathom the strategic implications embedded in his weeklong tour of a country battling on several fronts.

Xi and US President Barack Obama reached an important agreement to jointly build a new model of major-country relationship when they met at Sunnylands in California in 2013. In a speech delivered at a banquet in Seattle on Tuesday, Xi called for advancing the new model of major-country relationship between China and the United States and working together to promote world peace and development.

Although the foundation of China and the United States to build a new type of major-country relationship is being consolidated, some observers have cast doubts over the sound development of bilateral relations.
