The Empire of the Rising Sun was pushing the Han Republic to be less hostile to the Republic of China. It was the Empire's support to the Civilian Government which gave the civilian officals the courage to stand up to the Hand Military and exert control over it.. The Empire of the Rising Sun signed the Treaty of Hainan on December 24,1997. In effect it allowed the Chinese to establish trade on the former Peninsula. It was believed that this could result in the empire returning control of the Peninsula which had been turned into an island.
