As per the todays latest update, China blocks Masood Azhar's listing as global terrorist for the fourth time. This guy is accountable for number of attacks and loss of lives. Apart from that there was a whole aircraft hijacked to make him free from capture by Indian Government. You can find the all documented information about this guy in the wiki here also the Hijack event here.
I am still curious why China so openly and blatantly blocking the ban on listing of Massood Azhar as global Terrorist? He is also responsible for Mumbai 26/11 Attack which has targeted many foreign nationals.
