Han-Chinese nationalists want han-🇨🇳China´s empire to take back the lands they lost to 🇷🇺 Romanov/Bolshevik empires .

Would be so much cheaper than Formosa and come with a deep water port and closer to the US market. I think this is a strategic goal for commie han- China and much likelier to happen than Formosa.
ps but, Hands off Karafuto/Sakhalin.. That's for Japan !!
