They were trying to conditionally surrender. Meaning they were calling the terms of the surrender.
In theirmfavor as to what they had done previously,,in terms of gains and possibly comtinued fighting against the chinese.
Ah. We were to accept their surrender by collaborating with them.
They were originally looking for an armistice, or a negotiated end to the war. That in no way is a surrender.
WWI ended in armistice. Later a peace treaty was signed. Germany never surrendered. This was the objective of the Japanese offers to negotiate.
