Responding to reports that China has asked the US to respect Pakistan' sovereignty in the aftermath of the Bin Laden operation, Chinese Foreign Ministry spokesperson Jiang Yu used a May 19 press briefing to state Beijing' categorical demand that the "sovereignty and territorial integrity of Pakistan must be respected." According to Pakistani diplomatic sources cited by the Times of India, China has "warned in unequivocal terms that any attack on Pakistan would be construed as an attack on China." This ultimatum was reportedly delivered at the May 9 China-US strategic dialogue and economic talks in Washington, where the Chinese delegation was led by Vice Prime Minister Wang Qishan and State Councilor Dai Bingguo.1 Chinese warnings are implicitly backed up by that nation' nuclear missiles, including an estimated 66 ICBMs, some capable of striking the United States, plus 118 intermediate-range missiles, 36 submarine-launched missiles, and numerous shorter-range systems.
Support from China is seen by regional observers as critically important for Pakistan, which is otherwise caught in a pincers between the US and India: "If US and Indian pressure continues, Pakistan can say 'China is behind us. Don't think we are isolated, we have a potential superpower with us,'" Talat Masood, a political analyst and retired Pakistani general, told AFP.2
