I got the pic from the Chinese report below. it upset them cuz they think it's anti Japanese. The Korean tiger is some kind of symbol of Japanese cruelty. Apparently koreans believe it was extinct due o Japanese invaders. So Japanese right wingers organise anti Korean march nearby
This whole thing is actually mildly beneficial to China:
1. Japan is working really hard right now from all angles trying to get the US to stay in East Asia, as US is showing signs of wanting to scale back involvement.
2. Ideally to achieve this they should team up with South Korea in this effort
3. Election season is coming in South Korea, and the opposition party has just come out and said "the other mob are full of collaborators from WW2 that were never properly purged, it's high time to revisit this and sort it out"
4. Now that Japanese right wing have come out flying the imperial flag, no one from South Korea can be seen to be too cosy with the Japanese, therefore there could be no coordination between the two countries
