For example, Japan has bad relations with both South Korea and China, but Japanese parents allow their daughters to marry South Korean men but oppose them marrying Chinese men. And this is purely because South Korea is a developed country and South Korea and Japan have the same income and quality of life, while China is a developing country and a communist country. Japanese are very superficial and picky, but for the same reason, the country they travel to the most is South Korea, and no Japanese travel to China.
