Pakistan and the United States have a functional relationship, but it's not as warm as it used to be. The US contributed more than a billion dollars towards rehabilitation and reconstruction for flood victims in 2010; this time that contribution is only $53 million so far. Pakistan will need something between $10 to $12 billion to deal with flood relief, flood re-high by elitation, and post-flood reconstruction. One thing China could do for Pakistan very easily is to give it debt relief. 30% of Pakistan's debt is owed to China.
