Japan proposed a plan during negotiations that the Okinawa main island would belong to Japan and the Yeyma islands and Miyako-jima island to China and that Japan-Qing Treaty of Friendship be revised with an additional clause to grant Japan a most-favored nation treatment (proposal for divisional rule over the islands and a revision to the treaty), and this proposal was once accepted.
