PLAAF haven't inducted the FC-1 Block I, BUT they have hundreds of light 3rd gen AC that need to be phased out, they may choose later blocks of FC-1.
And the reason for not choosing FC-1 Block I is justified, since they already have a wide range of 4th gen... J-10/A/B/BS, J-11/A/B/BS, J-15, JH-7 variant, Su-30MKK/MK2 and Su-27SK/UBK.
PLAAF has chosen F-7Gs instead of FC-1 alongwith its J-10 and J-11. F-7G is a known and battle proof platform which the Chinese will not abandon. Rather, it is possible that the Chinese will produce less number of J-10s and J-20s, and will depend rather on its F-7Gs.
One more point. The climbing rate of F-7BG is about 195m/s and not 150m/s as I have mentioned earlier. Note the quotation from a defence article:
"---------Based on the F-7MG electronic technology demonstrator, it (F-7PG) features various upgrades to meet PAF's requirements, including a one-piece windshield, Italian Grifo-7PG PD radar (search 55km, track 37km, single target track), new color CRT displays (EFIS), HUD, HOTAS control, new air data computer, TACAN, PL-9C IR-guided AAM, WP-13F(B) turbojet (13,200lb w/ afterburning) plus two 30mm cannons (compared to one on J-7E/G).
Its maximum climb rate is 38,300ft/min (195m/s), combat radius is 850km (hi-hi-hi air-superiority role) and maximum load is 1,800kg. The new double-delta wing suggests the same design on J-7E has proven successful. However, since its basic design of Mig-21F has been more than 40 years old, this approach did not fundamentally change the overall performance. Pakistan ordered 57 F-7PGs in early 2000. These F-7PGs have replaced J-6/Mig-19 and will counter India's Mig-21bis/Bison fleet. 48 were delivered to Pakistan by the end of 2002.
Besides Pakistani AF, Namibian AF ordered 12 F-7NMs in August 2005. All were delivered in 2006. These are equipped with Italian Grifo-7MG radar. Bangladesh AF also ordered 12 F-7BGs in 2005. All were delivered 2006. ------------. The latest news (November 2011) suggested that Bangladesh is considering to acquire 16 IMPROVED F-7BGs in 2012 featuring a glass cockpit with 3 MFDs and HOTAS". (end of quotation)
I do not think BAF has made a mistake by opting for BGI grade F-7s which will also be BVR capable and there will be a total of seven hardpoints. A fighter jet is not a transport plane. It should carry only the weapons that it is supposed to carry, that's all.
JFT has two additional adavantages. One is its radius of action is longer than the BGI, and its loading capacity is higher than a BG or a BGI. But, in order to defend a small country like BD, BAF need no larger fuel tank. Its carrying capacity need not also be increased, because its ammunitions are limited for its mission.
So, I think, BAF decision is correct by not opting for a JFT platform, because BAF has a little opportunity to use this plane at its optimum.
