A lot of Japanese like a lot of ktards here has always had bad perception of China 

So, why beat around the bush anymore when Japan had stated their official stand. What's the point trying to be nice when the other side are outright challenging you.

Let's be honest here, Japanese PM cause all the trouble and the only solution to cool down situation needs to come from her. Taiwan issue is a national issue to China and it actually threatened CCP indirectly. If CCP lose Taiwan, their standing among the people in China will be badly affected

You do know that China's stand is they will only go to war if Taiwan declare independence. That is the line they will not let Taiwan cross. Japan openly saying they will defend Taiwan is basically challenging one China policy and encouraging Taiwan's independence. Worse of all is Japan has a very bad reputation because of WW2. We will not understand because we never suffered a century of humiliation.

By your logic, I hope you will trust an ex-convict of armed robbery to look after your parent's house than to trust any other normal person.

Fact is Japanese massacred millions of East Asians and South East Asians during their occupation. They are clearly the aggressor during WW2. China did NOT kill millions by invading other country. Now that 80 years have passed, many are calling to move on because it is "in the past". Hence my comparison of Japan as an ex-robber is correct.

Accepting investments and have peace with Japan is akin to have peace with a robber and to do business. A rational thing to do if you don't have a choice, aka it is just a neighbour. But that not mean that when it comes to colonial tendencies, both China and Japan are the same. Far from it. One is an ex-robber, one stick to its own borders. Big difference.

On Taiwan, it is clearly China's internal matters. Since you brought up the Communique, it clearly states "The Government of the People's Republic of China reiterates that Taiwan is an inalienable part of the territory of the People's Republic of China. The Government of Japan fully understands and respects this stance of the Government of the People's Republic of China, and it firmly maintains its stand under Article 8 of the Potsdam Proclamation.". So who is Japan to interfere, regardless if China invades Taiwan or not?

Seems like you are selective in your reading of the Communique.

Find a clause in the Communique, don't just simply quote AI. Look at what I posted, it is clear that it is part of China. What else is there to pusing?
