This is from a while back but it should give "some" insight to what Pakistan is looking at and going for. It is about the FT-2000
Possible Missile Defenses Pakistani sources interviewed before the IDEAS show, as well as some recent published information, indicates that Pakistan’s leadership is very interested in obtaining a limited missile defense capability, especially to match any prospective Indian missile defenses that could be obtained from Israel or the U.S. This impression was confirmed by sources interviewed at the IDEAS show, while there was general reluctance to discuss the details of any future missile defense system. Published sources indicate that Pakistan is considering the purchase of a new active-guided version of the Chinese FT-2000 surface-to-air missile (SAM). In 1998 Chinese sources disclosed to the author that this SAM, originally designed with a passive seeker intended to attack electronic warfare aircraft, would eventually feature an active-guidance system that would have an anti-tactical ballistic missile (ATBM) capability. In 2003 the FT-2000A was disclosed in a Malaysian defense journal, complete with a new active phased-array radar for long-range missile guidance. The FT-2000 program is believed to stem from the HQ-9 program, which in turn has been described to the author as having benefited from Russian S-300 and U.S. Patriot PAC-2 SAM technology. In an ATBM mode, the FT-2000A might only be useful against short-range Indian missiles like the Prithvi or Dhanush, not against longer-range and thus faster Agni missiles.
FT-2000 SAM: Pakistan is showing great interest in its own ATBM, and a missile-intercept capable version of the Chinese FT-2000A appears to be the most likely choice.
