From June 8-9, the China-U.S. summit in Sunnylands, California attracted world attention because President Xi and President Obama decided to exchange in-depth views on global, regional and bilateral issues such as climate change, cyber-security, Sino-U.S. military ties, etc. The two leaders also touched the bilateral economic and trade ties, which have long been considered an anchor of a stable and strong Sino-U.S. relationship.

China’s adjustment of its investment-income deficit for 2011 exposes flaws in economic growth, but hasn’t raised as much concern as it should. Two statistics account for China’s negative net investment-income, high return on foreign investment and China’s foreign assets are mostly US dollars. Without fundamental change, it is hard to imagine a sable Chinese economy in the long-term future.

Though facing a largely uncertain prospect for its economic recovery after the 2008 financial tsunami, the US has for five years worked strenuously to promote economic restructuring, lay out plans for developing new industries globally and shore up its potential competitiveness for future growth.

One of the main breakthroughs from the informal summit between the leaders of China and the US was that Presidents Barack Obama and Xi Jinping did agree to work together on keeping North Korea in check and the Korean peninsula nuclear free, writes George Koo.

The United States Department of Defense’s most recent report on the People’s Liberation Army strained already heightened tensions between the US and China due to its focus on cyber security. Lu Jinghua argues the US needs to stop imagining cyber threats and start cooperating with China.
