The signing of the treaty did not signify a warming of relations, but an exit from total isolationism. It was a symptom of the Meiji Restoration, not an indicator of Sino-Japanese brotherly love. All nations that are not hermit states have formalized contact with their neighbours, whether their neighbours are their allies, or, in this case, their traditional enemies.

Even if it didn't signify warming relations. I don't see how you could possibly make that claim. Not having warm relations does not mean that they dislike each other. Also, sure. They were traditional enemies, but then there was the two century long period of isolation. Plus, the events during that time helped the Qing assume power as well. So once again, I don't see how you can claim that the relation between the two were cold during this time especially with the concept of to yo rentai ron (East Asian Alliance) was prevalent among the Japanese statesmen in this time period.
