As China reportedly mulls a ban on Japanese seafood amid a standoff between the Asian neighbors, Taiwan's leader shows support for Tokyo, with his lunch.

Japan has mostly toed the US line of “strategic ambiguity”, rarely speaking out and officially saying that the dispute can be resolved through dialogue.

China is trying to impose economic costs on Japan for wading into the issue of Taiwan. But experts say the escalating dispute could ultimately hurt China too.
