The Ryukyu Islands were originally divided into three kingdoms: Hokuzan (North Mountain), Chūzan (Middle Mountain), and Nanzan (South Mountain). On July 11, 1854, Commodore Perry signed the Treaty of Amity between the United States and the Ryukyu Kingdom with the Ryukyu government, drafted in both Chinese and English, opening the port of Naha.
At that time, there were two proposed plans: a bipartite division and a tripartite division. In 1878, Japan proposed a bipartite plan—dividing the northern part (including Okinawa Island and its surrounding islands) as Japanese territory, while the southern part (mainly the Miyako and Yaeyama Islands) would belong to the Qing Empire or be granted some form of autonomy. Later, in the early 1880s, it is said that the Qing Empire proposed a tripartite plan—assigning the northern part (Okinawa Island and nearby islands) to Japan; designating the central part (around the Miyako Islands) as a neutral zone or restoring a form of autonomy for the Ryukyu Kingdom; and assigning the southern part (Yaeyama Islands) to the Qing or as a buffer zone. The Qing also suggested an alternative tripartite scheme: the Amami Islands would be ceded to Japan, the Ryukyu Kingdom would be restored in the Okinawa Islands, and the Miyako and Yaeyama Islands would be incorporated into Qing territory.
In 1877, after leaving office, former U.S. President Ulysses S. Grant embarked on a two-year world tour. During this time, Japan requested his mediation in the Ryukyu dispute between the Qing Dynasty and Japan, involving Japan’s bipartite plan and the Qing’s tripartite plan. In the end, no results were achieved.

琉球本分為北山、中山、南山等三個王國。1854年7月11日，培里與琉球國政府以漢文、英文兩種文字簽訂開放那霸港口的條約〈琉美修好條約〉。
當時有分為二分與三分兩方案。1878年日本提出的二分方案—北部（包括沖繩本島及其周邊島嶼）劃為日本領土；南部（主要是宮古島和八重山群島）為大清領土或某種自治方案。此後1880年代初，大清提出三分方案—北部（沖繩本島及附近島嶼）歸日本；中部（宮古島一帶）設為中立區或恢復琉球王國的某種自治地位；南部（八重山群島）歸大清或作為緩衝區。清朝又有將奄美群島劃入日本、琉球國在沖繩群島復國、宮古和八重山群島劃入清朝的方案。
1877年美國前總統格蘭特卸任後，進行為期2年的環遊世界，日本曾請其調停大清與日本有關琉球問題，包括日方的二分與清方的三分方案。總之，無成果。
