Some more information and development history, the link dates back to 2006-07 but nice information.....................
October 1, 1988 between the PRC (the company NORINCO) and Pakistan (Heavy Industries Taxila) signed an agreement on joint development and production of the new main battle tank MBT-2000 (also known as "Type 90-II»). The program was approved by the Committee of Defense January 16, 1990, and in May was already signed the final contract. In parallel with the tests in China, Tank, "90-II» / MBT-2000 was tested in Pakistan. Manufacture of machinery was to be done at the factory F-711 company «Taxila», which until then jointly produce tanks "Type 59" , "Type 69" and "Type 85-IIM" .
first prototype promising Pakistani tank "Type 90-IIM», later received its own name "Al Khalid", was built in July 1991, and publicly demonstrated by China and Pakistan, as joint development. Virtually all of the prototypes "Al Khalid" are tanks "Type 90-II» / MBT-2000 in several different versions. After extensive testing, which began in 1992 and ended in the summer of 1998, it was decided to adopt for service option MBT "Al Khalid" the engine of Ukrainian origin 6TD-2.
In 2000, the Pakistani company «Taxila» completed the limited series production of the first pilot batch tank "Al Khalid." Only 15 cars were produced, which were sent to military units for trial operation.
Tank "Al-Khalid" ("Type 90-IIM») on trials in Pakistan
Main battle tank "Al Khalid" has some differences from the "Type 90-II» / MBT-2000. First, it has a hinged ERA in China, which gives the tank a distinctive appearance. Blocks of reactive armor on the front hull and turret projections similar to the tank, "90-II» with CLE, except the cheeks of the tower where the shelves are "corner", similar to the Russian and Ukrainian tanks. Additional blocks of reactive armor installed on the turret basket. The combat weight of the tank reaches 48 tons. It has been reported that in Pakistan the company is actively developing new armor alloys, which will later be used on the tank "Al Khalid."
The second major difference is the appearance and layout of the MTO, which established Ukrainian 6TD diesel engine and automatic transmission, summarized in a single unit. While the original project "Type 90-IIA» was supposed to use a French diesel engine «Unidiesel V» of 1500 hp, this option was dropped due to pressure from the U.S. and India on the French government (over the real reason, apparently, was the difference in the prices). Choosing to Ukrainian diesel did not unusual, since Pakistan has long cooperated with Ukraine in military terms, and previously purchased her 320 tanks T-84 with 6TD-2.
However, recently there have been reports that due to problems with its diesel forcing Ukrainians still offer Pakistan a good old 6TD, not 6TD-2,
