An article titled "An Unsentimental China Policy: The Case for Putting Vital Interests First" was published by the magazine Foreign Affairs in February, and argued that U.S. disengagement with China "would be a mistake."

The article was written by Graham Allison, professor at and founding dean of the Harvard Kennedy School and Fred Hu, founder and chair of Primavera Capital Group.

"As (Joe) Biden and his team develop a new strategy to meet the defining international challenge of this generation, many are urging them to give up on engagement altogether. That would be a mistake," the authors wrote.

The authors further pointed out that the U.S. administration should heed the central lesson of five decades of U.S. policy toward China, adding that it works best when focusing realistically on geopolitical objectives essential to protecting American interests.

It is worst when attempting to engage in political engineering to promote American values, said the article.

Meanwhile, the article reviewed the U.S. diplomatic policies with China during past years, and noted that the Biden administration should find lessons instructive.

"When pursuing geopolitical objectives, engagement has succeeded more often than failed," said the article.

"Those who advocate regime change in China to promote democracy are as misguided as those who pushed wars in the Middle East in pursuit of the same objective," it added.

The article then stressed that "policies of openness and integration" have been engines of economic growth for the world, and they will "remain essential for a successful future."
