Measurements meant to mend diplomatic ties between Japan and China, known as "Panda Diplomacy," have faced significant difficulties as relations sour. The "Zero Panda" issue refers to Japan's struggle with the declining panda population in its zoos, as negotiations for more pandas from China have stalled. The ongoing political disagreements between the two nations have exacerbated this wildlife issue, leaving both conservation efforts and diplomatic strategies in troubled waters.

In Japan, the panda population in zoos has been a significant source of national pride and an appeal to foreign tourists. However, the pandas are imported from China as a diplomatic gesture, complicating the situation amid tense relations. The deadlock over increasing the panda imports underscores public concern over China's influence and the interplay between wildlife conservation and politics.

In the US and EU, diplomacy has been less animal-dependent, with policies revolving more around economic, military, or cultural aspects. However, such exchanges work similarly to "Panda Diplomacy" in that they aim to foster goodwill and improve international relations. The issue here parallels the difficulties in agreements on various diplomatic fronts encountered in Western countries.
