Full coverage: G20 Hangzhou Summit

US President Barack Obama will also attend the G20 summit in Hangzhou, one of his last major international trips before his presidency ends in January. CCTV reporter Roee Ruttenberg tells us about the expectations for his trip. 

The White House publicly confirmed President Barack Obama's attendance at the G20 summit less than two weeks ago. While an Obama spokesperson said on Friday there's still no word on the President's final schedule in China, administration officials have repeatedly stressed the importance of the trip, and their hopes that it will be a successful one.

Obama is expected to take part in the Leaders Summit in Hangzhou. And he'll also hold high-level bilateral talks with Chinese President Xi Jinping.

This will be among Obama's final appearances on the international stage as U.S. President. His second term ends in January. His administration is said to be keen to tie-up a few loose ends.

Sources say Washington and Beijing could each ratify the landmark COP-21 climate deal, reached in Paris last December. They may do so - even before the G20 begins - laying the groundwork for substantial clean energy talks at the Hangzhou summit. Washington is expected to call on other countries to ratify the deal to help ensure the treaty goes into force, perhaps before Obama leaves the White House.

China is expected to focus on global economy recovery. Obama will likely try to highlight economic growth since he took office.

The White House says Obama will, quote: "underscore the importance of G20 cooperation in promoting a level playing field and broad-based economic opportunity.

Obama took office back in 2009. This will be his eleventh trip to the region as U.S. President, as part of his administration's rebalance, or so-called pivot, to Asia. It's a policy that has often put Washington at odds with Beijing.

At the last U.S.-China talks in Beijing in June, the two sides clashed on a handful of friction points, including the South China Sea and the deployment of U.S. anti-ballistic missiles in South Korea. These issues are likely to come up again when Presidents Obama and Xi meet.

Along with President Xi, Obama has stressed how the world's two biggest economies have worked together on climate change and nuclear security. White House officials suggest Obama will want his final trip to China as President to end on a positive note.
