The strengthened Chinese invasion force, after regrouping under a new commander, reaches Ava in 1446 and orders Narapati to surrender and deliver over the Shan chief Thonganbwa, who has taken refuge here.

Narapati negotiates a deal to hand over Thonganbwa if the Chinese help him subdue Yamethin first.

The Chinese agree, and together with a contingent of troops from Ava, conquer Yamethin.

Thonganbwa, recognizing eventual Shan defeat, complies, but soon commits suicide; is dead body is handed over to the Chinese in early 1446.

Narapati maintains that he has not accepted Chinese suzerainty, but the Chinese consider the handover of the body as Ava's recognition of Chinese rule.
