BEIJING (AP) — Four decades after the U.S. established diplomatic ties with Communist China, the relationship between the two may have reached a turning point.
Tensions have reached new heights on what has always been a rocky road as the ambitions of a rising superpower increasingly clash with those of the established one. China ordered the closing of the U.S. Consulate in the southwestern city of Chengdu on Friday, in rapid retaliation for the closing of its consulate in Houston.
Two weeks ago, Chinese Foreign Minister Wang Yi asked aloud if relations could stay on track. On Thursday, U.S. Secretary of State Mike Pompeo delivered an answer: The time has come to change course.
"The old paradigm of blind engagement with China simply won't get it done," he said in a speech at the Richard Nixon Presidential Library in Southern California. "We must not continue it. We must not return to it."
It was Nixon's visit to China in 1972, the first by an American president since the Communists took power in 1949, that upended a Cold War paradigm and paved the way for the normalization of relations in 1979.
The United States had been a close ally of then-Chinese leader Chiang Kai-shek in World War II and for three decades recognized Taiwan as the government of China after Chiang fled there when he lost control of the mainland in 1949.
Relations between Washington and the Communist government in Beijing began to thaw in the 1970s, as China's ties with the Soviet Union deteriorated and leader Mao Zedong sought a counterweight to its more powerful neighbor.
A new leader, Deng Xiaoping, visited the U.S. in 1979 after the establishment of diplomatic ties, smiling in photos as he tried on a cowboy hat in Texas. The Houston consulate that is being closed opened later the same year. It was China's first in the United States.
Setting aside political differences, the U.S. and China promoted economic, social and cultural ties that were briefly interrupted a decade later by China's military crackdown on the 1989 pro-democracy demonstrations in Beijing's Tiananmen Square.
Economic links grew exponentially in the following years, with heavy investment by U.S. businesses in China and an accompanying Chinese trade surplus that has reached $350 billion annually.
The relationship was punctuated by bouts of tension. The U.S. continues to support Taiwan militarily, and the Clinton administration sent an aircraft carrier through the Taiwan Strait in 1996 after China fired missiles toward the island.
In 2001, a Chinese fighter jet and a U.S. Navy surveillance plane collided over the South China Sea, a vital shipping lane in the Asia-Pacific region. China detained the U.S. crew for days after its plane made an emergency landing at a Chinese base.
As China has grown into the world's second-largest economy, behind only the U.S., it is increasingly viewed as a competitor, both economically and militarily, and a potential challenger to the Western-led democratic model that has dominated the post-World War II era.
Election-year politics in the U.S. are fanning the flames as President Donald Trump appears to be using friction with China to drum up support among his base. Whether or not he is reelected in November, underlying differences will remain.
"We are looking at a structural change in the relationship, which will continue even if Trump does not get a second term," said Steve Tsang, director of the China Institute at London's School of Oriental and African Studies.
