How many countries are there in China?

Contiguous, with Myanmar, Laos and Vietnam to the south. Then there's China's non-aligned, de facto allies, Pakistan, Burma, Sri Lanka, Bangladesh, and Sudan. North Korea is not an ally, just a dangerous neighbor. Among the better countries: 1. Pakistan (historical reasons: 2 or 3 decades ago when India and the US fought against China, Pakistan was on China's side. 2. Most African countries, West Asia and most developing countries. (It can be said that the weaker countries share the same disease, help each other against the strong, right) potential hostile countries: 1. the United States (trade friction and institutional confrontation) 2. Japan (historical hatred can not be eliminated within a short period of time) 3. the European Union (the reasons are similar to the U.S., the St. Meditation will not be interpreted) 4. India, Bhutan (the rise of the countries against each other and the history of hatred) India has consistently China as the biggest imaginary enemy, and Bhutan is a vassal state of India. 5. India is India's vassal state. 5. Russia: at present is to cooperate against the United States of America's "strategic partnership", but each other have a heart, after all, the land is directly connected to the nuclear powers, each other have to be on the defensive. Russia has also been afraid of Chinese immigrants settling in large numbers in Siberia, leading to territorial disputes. Kazakhstan, Kyrgyzstan, Tajikistan: the former Soviet Union **** and countries, basically belong to the Russian sphere of influence, but the United States through the war in Afghanistan also infiltrated. China has some economic cooperation with these countries, and has also established the Shanghai Cooperation Organization for military cooperation, but China is unable to exert much political influence over them, and is somewhat out of reach. The rightist radical forces in these countries are also hostile to China. Pakistan, Nepal, Myanmar, Laos: China's traditional friendly countries, Pakistan against India all rely on China's military support, but in recent years the minibus and the United States is also very close, in case of conflict between the United States and China is really hard to say which side of the Pakistani defection. Nepal, Myanmar, and Laos can be seen as China's vassal states, and China has given their governments huge political, military, and economic support, but they all have unstable separatist forces in their countries, including the Maoist guerrillas in Nepal (who believe in Mao Zedong's ideology and want to overthrow the monarchical Nepalese government), and the guerrillas in Myanmar's ****-producing party and Shan State (who are involved in the drug business in the Golden Triangle), all of which have left the government forces in a state of confusion. Thailand: a traditional ally of Britain and the US, with good economic cooperation with China in recent years, but still relatively discriminated against by the Chinese within Thailand.
