Let's tame our emotions and look at things rationally.
1. True, the Chinese never used the T-72, but the
early variant of the Type 96 did use some design moieties found on the former (which was most likely obtained from captured or donated T-72s). The improved 3rd-generation
Type 96A, however, did away with many of these elements by incorporating far newer subsystems, including technologies from the Type 99.
2. The Altay has little to do with the Leopard 2, and was instead developed in partnership with the same South Korean company (
Hyundai Rotem) that designed the K2. Most subsystems, including main gun (
MKEK), armor (
Roketsan), and electronics (
Aselsan), are developed by Turkish contractors. Granted, the tank does seem to bear a faint semblance of the South Korean K2, but Turkish companies were responsible for researching and ultimately deploying all of its technologies.
Its engine is slated to be replaced by a domestic powerplant developed by
TUMOSAN, so any German control on its export of MTU engines is unlikely to affect future exports of the Altay:
