The same source also mentions that prior to the Mongol conquest, Tibet was always an independent country. After the Mongol conquest, they were both ruled by the Mongols as “colonies” or protectorates as the case might be.
Your argument is akin to the Canadians claiming control over the USA because both countries were ruled by the same colonial power a while ago....LOL
Exactly! The question then becomes who has a greater claim over the U.S. the Brits or the Spanish? ROTFLOL
