BEIJING - President Obama has emerged from his first trip to China with no big breakthroughs on important issues, such as Iran’s nuclear program or China’s currency. Yet after two days of talks with the United States’ biggest creditor, the administration asserted that relations between the two countries are at “at an all-time high.”

Although one concrete advance emerged — that the United States may offer a target for carbon-emission cuts to boost climate negotiations in Copenhagen next month if China offers its own proposal — it was a relatively small step for a new president who had campaigned on a promise to enact far-reaching change in U.S. diplomatic interactions.

If there was any significant change during this trip, in fact, it was in the United States’ newly conciliatory and sometimes laudatory tone. In a joint appearance with President Hu Jintao on Tuesday, Obama hailed China as an economic partner that has “proved critical in our effort to pull ourselves out of the worst recession in generations.” The day before, speaking to students in Shanghai, he described China’s rising prosperity as “an accompObama’s trip stood in stark contrast to visits by his predecessors. But this reflected not so much a policy shift by a new administration in Washington as a dramatic and much bigger change in the power dynamic, particularly in economics, over the past decade — a change that has been the central undercurrent of Obama’s swing through China this week.

lishment unparalleled in human history.”

Bill Clinton traded jibes
In 1998, when President Bill Clinton stood before television cameras in Beijing’s Great Hall of the People, the United States owed more money to Spain than to China and did more than twice as much trade with Mexico. At a freewheeling news conference, Clinton criticized China’s military crackdown a decade earlier in Tiananmen Square and traded spirited jibes with President Jiang Zemin.

On Tuesday, Obama stood in the same building alongside another Chinese leader. This time, with the United States in hock to China for more than $1 trillion dollars and flooded with Chinese-made goods, it was a Chinese-style news conference. Each leader read a prepared statement and eyed the other in silence. There were no questions.

Since leaving Washington last Thursday for an eight-day tour of Asia, Obama has occasionally nudged China on issues such as Tibet and Internet censorship. But he has more often trumpeted China’s achievements and pleaded with Beijing for increased help on the world stage.

China returned the effusiveness in its music selection at a state dinner for Obama on Tuesday night. The People’s Liberation Army serenaded him and other U.S. officials with “I Just Called to Say I Love You,” “In the Mood” and “We Are the World,” as Obama and Secretary of State Hillary Rodham Clinton sat on either side of the Chinese president over a steak dinner.

In many ways, the United States and China have never been closer, as reflected in a raft of joint projects outlined Tuesday, the second day of Obama’s visit here. In addition to cooperation to curb global warming, these included previously announced and now reinvigorated efforts on stem-cell research, crime prevention and military contacts. But with the rituals and even the substance of the two countries’ interactions increasingly on Chinese terms, Obama advisers insisted that their overtures and polite tone are in pursuit of long-term results, a reflection of China’s growing importance.

‘Get traction’
The U.S. ambassador to Beijing, Jon Huntsman Jr., a former Republican governor of Utah who speaks fluent Chinese, said the goal is to “make sure that we are able to connect with the Chinese bureaucracy in ways that actually allow us to get traction.”
