A Chinese delegation led by Vice Premier Wang Yang and State Councilor Yang Jiechi arrived here Tuesday for the fifth China-U.S. Strategic and Economic Dialogue ( S&ED), which will start Wednesday.

Acting as special representatives of Chinese President Xi Jinping, Wang and Yang will co-chair the two-day dialogue with U.S. President Barack Obama's special representatives Secretary of State John Kerry and Treasury Secretary Jacob Lew. Wang and Lew will co-chair the economic track talks, while Yang and Kerry will co-host the strategic track talks.

During the two days, leading officials from more than 20 departments and ministries of both countries will hold a series of talks and consultations on a wide range of political, security, economic and financial topics that cover major bilateral, regional and international issues of mutual concern.

The two sides will hold two special joint sessions on climate change and energy security, in addition to the third strategic security dialogue. Notably, the cyber working group will convene for the first time to discuss the issue of cyber security, which threatens to strain bilateral ties recently.

Top on the agenda will be discussions on ways to implement the consensus on building a new type of major-country relationship based on mutual respect and win-win cooperation, as reached by the two presidents at their historic summit held in California last month.
