Of all the global flash points  between Super Powers, I would say the most tension right now is in Pakistan in the Contest between the US and China.
**
The leaders of Pakistan fear the are losing control of their country and are running to China for help.
**
China in return has given Pakistan 50 JF-17  jet fighters
**
China has asked the US to please honor Pakistan Sovereignty.
 **
Pakistan has come out and said it welcome’s China’s help in building a Naval Base at the strategic port of
Gwadar Pakistan.
