China has officially put the United States on  notice that Washington’s planned attack on Pakistan will be interpreted  as an act of aggression against Beijing. This blunt warning represents  the first known strategic ultimatum received by the United States in  half a century, going back to Soviet warnings during the Berlin crisis  of 1958-1961, and indicates the grave danger of general war growing out  of the US-Pakistan confrontation.   
“Any Attack on Pakistan Would be Construed as an Attack on China”
    
Responding to reports that China has asked  the US to respect Pakistan’s sovereignty in the aftermath of the Bin  Laden operation, Chinese Foreign Ministry spokesperson Jiang Yu used a  May 19 press briefing to state Beijing’s 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. Chinese warnings are  implicitly backed up by that nation’s 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. 
  
The Chinese ultimatum came during the visit  of Pakistani Prime Minister Gilani in Beijing, during which the host  government announced the transfer of 50 state-of-the-art JF-17 fighter  jets to Pakistan, immediately and without cost. Before his departure,  Gilani had stressed the importance of the Pakistan-China alliance,  proclaiming: “We are proud to have China as our best and most trusted  friend. And China will always find Pakistan standing beside it at all  times….When we speak of this friendship as being taller than the  Himalayas and deeper than the oceans it truly captures the essence of  our relationship.” These remarks were greeted by whining from US  spokesmen, including Idaho Republican Senator Risch.
