When you say pro-West kleptocrats, do you mean folks like Boris Yeltsin?
Honestly, pro-west Kleptocrats within the CCP's ranks constitute greater threats to the Party State than Taiwan or other geopolitical foes. In fact, what you have now in China is a tacit alliance between Zhi Rens, pro-West kleptocrats and their families (who apparently became pro-west after losing influence to Xi's men in political struggles), and western liberal medias. China really needs to break this powerful - but relatively invisible - alliance. Otherwise, a Chinese Boris Yeltsin (yes, think Hu Yaobang, who even called for withdrawing troops from Tibet, while Zhi Ren students were willing to eat bullets for him) leading a group of Zhi Rens could cause serious harm to China's future development. Think about it. While most would blame Gorbachev for the collapse of the USSR, but it was pro-west kleptocrats and Zhi Rens like Yeltsin who actually shot the USSR in the back despite the facts that the people of Russia, Ukraine, and Belarus voted to preserve the USSR. The irony is that Yeltsin was even more autocratic than CPSU's elite around Gorbachev. I'm afraid China's pro-west kleptocrats are no better, if not worse due to possible economic ties to the West.
The bottom line is that pro-west kleptocrats are no democrats. Once in power, they would simply rule with an iron fist on behalf of western MNCs, with Zhi Rens serving as the colonial hitmen and propagandists.
