This is how people call it ignorant.
China has 14 land connected neighbor countries. If Japan is included in your counting, there are 15.
In recent history, China fought with (count-clockwise) Vietnam, Japan, 0.5 Korea, Soviet Union,and India. Figure out the percentage yourself.
In present, China has good relationship with all those countries except India, but internet Chinese do have problems with Indian-Korean such as “Korean” in this forum, and some internet Vietnamese.
In contrast, India still has problem with China and Pakistan, the two major neighbors, and some lesser problems with BD and Sri Lankar. India has only 6 land connected neighbors, and the 50% hostility persists up to now. That is the problem.
Stop being hilarious, buddy, though we know illiteracy has its heavy toll in your country.
Tajikistan, Kazhakistan, Kyrgyztan were part of Soviet Union when China went to war against them. So add those countries to your list.
