Folks, I've said it before, I'll say it again: the ROC doesn't claim Mongolia anymore. They recognized Mongolia as an independent state in 2002, and in the process also gave up their claims on Tuva. Which I believe means that they just claim the PRC and the disputed territories the PRC also claims, so certainly not 'vastly more land'. The ROC's claims are a joke nowadays, but there's no excuse to be inaccurate.
