Mitt Romney responded in tones appropriate for a bitter foe. Writing in The Wall Street Journal, he accused President Barack Obama of "weakness" that "has only encouraged Chinese assertiveness" while serving to "embolden China's leaders at the expense of greater liberty."
As for our economic ties, he wrote, "A trade war with China is the last thing I want, but I cannot tolerate our current trade surrender."
Martial metaphors like that give the impression we are locked in a deadly struggle with Beijing. For that reason, it's no surprise that in January of last year, China ranked first in a Pew Center poll as the country representing the greatest danger to the United States. In the latest one, it finished second only to Iran.
The perception of Iran is understandable, given that our leaders seem bent on taking us to war there. But China? If we're going to have adversaries, China is the best kind to have.
For one thing, it's no match for us militarily. The United States spends between two and nine times as much on defense as China. We have 11 aircraft carriers; they have one -- which they bought, used, from Ukraine. We have nearly 3,700 modern combat aircraft to their 307.
"We don't view China as a direct threat," Vice Adm. Scott Van Buskirk, commander of the U.S. Seventh Fleet, said last year. "To look at China through the lens of an adversary would be counterproductive."
It's true that China has been upgrading its defense forces. But that's what you would expect of a country that has gotten much richer in the past few decades.
It's also what you would expect of a country surrounded by neighbors with which it has had military conflicts -- including Russia, Japan, India and Vietnam. Not to mention that it has 9,000 miles of coastline on the Pacific Ocean, which is effectively owned and operated by the U.S. Navy.
Like any normal regional power, China aspires to have some capacity to dictate to others rather than be dictated to. That ambition could bring it to blows with the United States over Taiwan or over free passage in the South China Sea.
Rising powers often collide with established powers, which means there is certainly potential for China to clash with the United States. But the two sides have proved able to peacefully manage their chief disagreement, Taiwan, decade after decade.
