Hello,
My EMS parcel EA062049556CN has been booked from Shenzen to Pakistan on 18th April 2016. Today is 2nd May 2016, but my parcel is still in China. I have looked for in Pakistan Custom and Post departments. These departments and the tracking information said, your parcel is still in Guanzhou. It contains some VISA documents, I am worried, Has China Post lost my parcel?
Cheers,

And the last tracking is:

3. You know that you can track your parcel at the Pakistan Post on this site:

The last tracking shows this:

4. I suspect it should not be to long before your parcel shows up in Pakistan, It might already be at the Pakistan Customs Office getting clear.

Hope this help.
