The second Sino-U. S. Strategic and Economic Dialogue next month in Beijing will be crucial for the future of their relations, Chinese analysts have said.

China Daily reported on Wednesday that Yuan Peng, head of U. S. studies at the China Institutes of Contemporary International Relations, said, "Sino-U. S. relations are now at a turning point and the meeting is key for both parties to determine their future strategies. The discussion will include more topics than in 2009."

It was also reported that trade relations, the Iran nuclear issue and revaluation of Chinese currency are likely to be the main topics on the agenda at the two-day meeting in late May. The first round of the talks, established by President Barack Obama and his Chinese counterpart Hu Jintao, was held last August in Washington.

According to the report, relations between the two countries are strained because of issues such as trade disputes, U. S. demand on Beijing to allow its yuan to appreciate to balance trade, the $6.4 billion U. S. arms sales to Taiwan and Obama's meeting with Tibetan spiritual leader the Dalai Lama.

Beijing will not let other countries dictate on the currency question, Yuan told China Daily.

He blamed the United States for the strained relations, citing the Taiwan arms sales and the Dalai meeting, Shi Yinhong, an expert on American studies at the Renmin University, told China Daily. (With Inputs from Agencies)
