So if you go to Europe with the same culture, no matter where you go, you will find many things very similar, including palaces, churches, museums and so on. The exhibits in the museum are similar, and the religious paintings in history are exactly the same as the epic paintings. Language and money are also one.
In addition, when it comes to economy, the economic differences among countries are relatively small. Of course, Germany and France are still much better than "European pigs" such as Portugal, Italy, Greece, Spain and Ireland. Although these five countries have held back the European Union and even Greece has gone bankrupt, the economic gap between them is much smaller than that between Asian countries.
Asia has both countries with huge economies such as China, Japanese and Korean, and poor countries such as Cambodian and Bangladeshi, so it is difficult to unite. In terms of beliefs in Asia, there are Islam, Buddhism, Confucianism, Christianity and Catholicism. This cultural difference also determines that the Asian alliance is difficult to achieve.
Moreover, as an Asian economic power, Japan has always adhered to the policy of leaving Asia and entering Europe, mainly in Europe and the United States, and has no intention of participating in Asian affairs. There are too many grievances between Asian countries in history. The problems between Japan and Southeast Asian countries left over from the Second World War, such as the Sino-Japanese issue, the Asahi issue, the Korea-DPRK dispute left over from the Korean War, and the territorial dispute and the South China Sea issue that have always existed between China and India. Are stumbling blocks that hinder Asian countries from moving towards unity.
Therefore, we should not see the emergence of "Asian Union" or "Asian Union" in a short time.
