Now that China has been confirmed to have a prototype of a stealth fighter flying earlier than US predicted(US predicted that prototypes won't fly until 2015 or above that), USA might sell Taiwan F-35s in the near future to support the separation of Taiwan from Chinese Motherland. So in order to counter this possible move by USA, China must make a stern message that if USA sells Taiwan F-35, China will sell J-20 to Iran or North Korea as a bargaining chip, or China will consider that move by USA as a No-1 threat to its national security and use that as justification to ramp up military spending higher than what China originally planned or China should speed up deployment of J-20 AND invest in more advanced cruise missiles and surface ships as well as preparing to deploy more space-based sensors to keep a stern watch on US deployments in region.
Also China should discourage more F-16 sales to Taiwan by threatening to sell 28 J-20s to North Korea or Iran in a 20-year pay-by-installments deal if USA sells Taiwan more F-16s. China must do all it can to prevent Taiwan from gaining more advanced weapons since the more advanced weapons Taiwan thinks it has that can successfully repel a Chinese liberation attack, the more emboldened it would make Taiwan to declare indenpence. The military gap between China and Taiwan must be like the difference between Heaven and Earth to deter Taiwan Independence.
