The spats between the United States and China appear to be getting more numerous and more serious. The Chinese objected in strong terms to Washington’s latest arms deal with Taiwan and threatened to take sanctions against those firms involved. President Obama recently accused the Chinese of currency manipulation. At Davos, Larry Summers, the director of the White House’s National Economic Council, made an oblique attack on China by referring to mercantilist policies. The disagreement between China and the US at December’s Copenhagen climate summit has continued to reverberate. The Chinese government reacted strongly to Google’s claims – supported by the US administration – that cyberattacks against it had originated in China and its statement that it would no longer cooperate with government censorship of the Internet. The US has been increasingly critical of China’s unwillingness to agree to sanctions against Iran. And finally the Chinese government is accusing the US administration of interference in its internal affairs by insisting on the meeting this week between Barack Obama and the Dalai Lama in Washington.
