The PLA's large tank army from the sixties to the end of the Cold War was meant to fight the Soviet tank army. So its those T-59s, 69s and 80s against the likes of the T-62, T-64, T-72 and T-80. I think there was like 17 to 30 Soviet tank divisions that was ready to roll over from the border of Mongolia to Beijing. That's quite a fight the PLA was facing.
The T-80 was a particular concern. The developments that led to the Type 90, 96 and eventually to the 98 and 99 was inspired trying to beat this tank. And even after the Cold War ended, and relations thawed with what is now the Russian Republic, the PLA was eager to get some T-80s for examination under the guise of "purchase".
The need for a large tank army in China is not for Taiwan, but an insurance against future resurgent Russia that may turn enemy to China again, which is not that implausible, considering how threatened the Russians feel about the gravity of Chinese economic power and outnumbering them in the Far East. They would think that the Chinese is out to grab their Siberian resources.
