As king, Binnya Ran largely kept his kingdom at peace for much of his 20-year reign when Ava was struggling to keep its territories intact.
When Ava forces came to occupy Dala opposite Dagon, Binnya Ran presented his elder sister Shin Sawbu to Thihathu, and bought peace.
[7] His reign name, as reported in Mon language inscriptions, was Rama Razadarit (ရာမ ရာဇာဓိရာဇ်; Pali: Rāma Rājādhirāj).
[6] In the same year, Thinkhaya III, the governor of Toungoo sought Binnya Ran's alliance against Ava by presenting a daughter.
[6][9] Mohnyin Thado broke up the alliance by giving a niece, Soe Min Wimala Dewi, to Binnya Ran.
[10] For the remainder of his reign, he was content to see Ava had its hands full with Ming Chinese invasions and Shan raids.
