中国

Why are you guys wasting tens of billions of dollars giving away to the Chinese every year, who only thank you this way? Why don't you stop it because they are sending you a clear message that they don't care about it. Do you know how much tax you are paying to fund such ODAs? To me, Japanese seem to be weird people who are willing to pay to get bullied. It is YOU TAXPAYER's right to claim such abuses.

Same thing for investments. To those Japanese companies investing in China - you will never get returns, and instead you will end up letting them steal your intellectual property and take your factory over, given your naivete dealing with foreigners. There should be better places to invest in this world.
