Concrete results and fair treatment are the most important requirements for a successful third round of the China-US Strategic and Economic Dialogue (S&ED) that opened in Washington on Monday, experts say.

The dialogue, initiated by President Hu Jintao and his US counterpart Barack Obama during their first meeting in London on the sidelines of the G20 financial summit two years ago, has provided a channel for the world's two largest economies to enhance in-depth communication.

"The US policy priorities were the major focus of the last two S&ED meetings and this round should represent China's core interests, as well as the voice of emerging and developing economies," said Zhang Yansheng, director of the Research Institute of Foreign Economic Relations, a think tank under the National Development and Reform Commission.

Song Hong, a senior researcher at the department of international trade with the Chinese Academy of Social Sciences, said China has moved more quickly than the US in realizing the commitments it made at the previous S&ED meetings.

"China has adopted relevant measures and delivered results in fulfilling its commitments, as discussed in the previous S&ED discussions. In comparison, we haven't seen concrete results on the US side," Song said.

For example, at the first meeting in July 2009, the US agreed to facilitate its high-tech exports to China and to push for China's early market economy status. These agreements were repeated at the second meeting, but they are still up in the air.

China can automatically acquire the status by 2016, according to rules of the World Trade Organization.

Long Guoqiang, a senior fellow at the research department of foreign economic relations at the Development Research Center under the State Council, China's Cabinet, said the restrictions that the US has put on high-tech exports to China has harmed US companies as more orders are being won by European and Japanese companies.

"It's clear that the US has lost a large number of business opportunities to its rivals and it's a great pity for US companies," he said.
