China has supported Argentina's claim to the Falkland Islands.

In 1982, when Argentina was ruled by murderous generals, supported by the US, they sent troops to seize the Falkland Islands, very much against the wishes of the British-descended people who lived there. The UK sent a fleet to liberate them.

The generals had used nationalism as a tool to distract the Argentine people from their crimes, but after losing the war, they couldn't hold on and Argentina became a democracy.

China's motive for taking a side in this dispute is surely to win Argentina's support in the new cold war. However, comparing the Falkland Islands to Taiwan is morally accurate. China wants to do to Taiwan the same thing that the Argentine generals did to the Falkland Islands: conquer and permanently rule an unwilling people.
