China's Xi arrives in Washington for first US state visit

Chinese President Xi Jinping arrived in Washington on September 24 for a state visit and talks with President Barack Obama that are expected to be clouded by differences over alleged Chinese cyber spying, Beijing's economic policies and territorial disputes in the East Sea.

Vice President Joe Biden greeted Xi and his wife as they landed at Andrews Air Force Base on the second leg of a weeklong trip that begin in Seattle. While there, the Chinese leader sought to reassure US companies that he is working to create a more favorable Chinese investment climate.

The two presidents will make a joint announcement on climate change on September 25 in a effort to build momentum toward a global climate change pact in Paris later this year.

The statement will build on the breakthrough announcement they made last year where the two countries set targets to either halt or reduce their emissions.

Planned announcement on September 25 puts the spotlight on new measures the countries will use to meet those targets, including a national carbon cap-and-trade system that China will launch in 2017.
