“this point I think we’ll just have to agree to disagree.”
I don’t understand what you disagree with.
“The ROC hasn’t renounced a 1-China policy...”
How can asking to join the UN and be in the UN along with China not be renouncing one China policy?
Same way the Koreans and Germans had both join and both still held a believe in eventual reunification with “their side” taking over the reunified country.
1 happened, the other likely will.
