BEIJING (Reuters) - The United States pressed China to implement structural reforms in its exchange rate and to modify its "aggressive behavior" in disputed waters during a preliminary round of bilateral talks on Tuesday, senior U.S. officials said.
The United States, led by U.S. Secretary of State John Kerry and Treasury Secretary Jack Lew, will also push China this week to resume cooperation on fighting cyber espionage and return to dialogue on internet issues, a senior U.S. official said.
The two-day annual Strategic and Economic Dialogue kicks off officially on Wednesday.
Lew has said he will push China to speed up economic reforms and do more to let the yuan rise against the dollar. Kerry will raise growing U.S. concerns over escalating tensions and China's "problematic behavior" in the South China Sea, officials said.
The dialogue will also touch on a bilateral investment treaty, which the U.S. hopes will loosen Beijing's restrictions to allow for a more level playing field for U.S. companies.
Washington has also begun to push for China to move to a market-driven exchange rate, another U.S. official said after initial discussions on Tuesday.
"Continued Chinese exchange rate reform will play a critical role in China's success," the official said.
As well as China's currency, North Korea's nuclear program and escalating tensions between China and neighbors in the South China Sea and with Japan in the East China Sea will be on the agenda.
The officials said the U.S. would call on China and other countries to clarify their territorial claims by ensuring they are consistent with international law.
"It is our observation that ambiguity about claims can be destabilizing and can lead to confrontation and even conflict," the official said.
The first official, speaking after the Tuesday discussions, said Washington saw "a pattern of aggressive behavior developing".
"It certainly does not benefit China in the long run," the official said. "We were very consistent in discussions today about that."
The United States has not taken sides in the disputes but has been critical of China's behavior in the oil-and-gas-rich South China Sea, where the Philippines, Vietnam, Malaysia, Brunei and Taiwan have overlapping territorial claims.
China, though, views the United States as encouraging its allies Vietnam and the Philippines to be more aggressive in the dispute.
Charges over hacking and Internet spying have increased tensions between the two countries. In May, Washington charged five Chinese military officers with hacking U.S. companies, prompting Beijing to suspend a Sino-U.S. working group on cyber issues. China has denied wrongdoing.
"We share an interest in a secure and predictable and orderly cyber environment," a senior U.S. administration official, who briefed reporters en route to Beijing.
"We see the bilateral U.S.-China working group as an important forum and vehicle for fulfilling our responsibilities and for making progress, so we certainly would like to see the earliest practical resumption of that forum."
Another U.S. official added: "One of the fundamental differences is on this question of the acceptability of cyber-enabled economic espionage, which the United States does not conduct. We need to come to a clear understanding with the Chinese about that. That is going to be essential to resolving our concerns about Chinese behavior."
Kerry will likely face an angry riposte from Chinese officials, who view the U.S. as hypocrites following revelations about Washington's own spying by former U.S. intelligence contractor Edward Snowden, and were angered in May when the U.S. charged the five Chinese military officers with hacking.
"We believe the U.S. side deliberately fabricated the facts," Chinese Assistant Foreign Minister Zheng Zeguang said on Monday, referring to the officers' indictment.
"This proves the U.S. side is not sincere in resolving Internet security issues through dialogue and cooperation."
The annual high-level talks between the U.S. and China have yielded few substantive agreements, in part because relations have grown more complex with China's increasing power.
Jia Qingguo, dean of the School of International Studies at Peking University who has advised the government on diplomatic issues, doesn't expect the talks to achieve much.
"I don't foresee many tangible results emerging. The relationship is at a low ebb. The role of SED now is to buttress the relationship to prevent a further deterioration," Jia said.
Still U.S. officials underscore the importance of the discussions to help ensure that the relationship doesn't drift towards confrontation.
"The U.S.-China relationship is a motion picture. It shouldn't be looked at as a snap shot," one official said. "It is that grand epic big Hollywood motion picture in which there are a lot of actors and a lot of interests at stake, and the trajectory of any particular issue takes time to play out."
U.S. officials cited climate change as one area where China and the United States could collaborate on a global issue.
"This is a classic example of an area of a global challenge for which U.S.-China cooperation is an essential ingredient of any long-term solution," one official added.
