Leaders' summits great way to boost bilateral relations

There is no doubt that President Xi Jinping and President Barack Obama, or any top Chinese and US leaders, should hold summit meetings more often.

The reason is quite simple. Such summits have the potential to change the dynamic of China-US relations for the better, as has been proved by the three summits between Xi and Obama.

The two leaders met in June 2013 in the California desert retreat of Sunnylands, in November 2014 in Yingtai, an imperial palace in Beijing's Zhongnanhai, the headquarter of China's central government, and last week in Blair House, across the street from the White House.
