Note that the Chinese have blamed Pakistan for Uighur Terrorism openly and have named the terrorists and confiscated their property as also impounding their bank accounts.

They never did it so openly before.

So, that means that they are getting tough with Pakistan?

Wrong.

It is to build up an excuse to demand operating bases in NWFP and FATA so that they can take on the Uighur rebels!

Even that is wrong.

They are wanting to plonk themselves between the US in Afghanistan and Pakistan so that Pakistan can breathe since the US will not then use Drones or carry out cross border raids. This will endear them to the Pakistani population.

Then they will carry out movement into Afghanistan once the US leaves so that their hold around the area become firm and their routes into Iran and its ports including Chahbahar (constructed by India) becomes a reality. And because of that they are supporting Iran against the US at all international forums.

China Seeking Counter-Uighur Military Bases In Pakistan?

In its effort to combat separatist Uighur groups, China is apparently seeking to establish military bases in the part of Pakistan that borders the Uighurs' home province of Xinjiang. That's according to Pakistani journalist Amir Mir, writing in Asia Times:

While Pakistan wants China to build a naval base at its southwestern seaport of Gwadar in Balochistan province, Beijing is more interested in setting up military bases either in the Federally Administered Tribal Areas (FATA) of Pakistan or in the Federally Administered Northern Areas (FANA) that border Xinjiang province.
