Why did Thailand become the only country in modern Asia that was not colonized?

Thailand was not colonized in modern times because it was good at taking advantage of the contradictions between powerful countries. Every time a war breaks out, Thailand will choose a powerful country as its backing to avoid being colonized by other countries. It can't be said that Thailand is very strong in modern history, but it can be said that it has discovered a loophole in the big game of war and avoided being colonized.

Throughout the history of modern Southeast Asia, Thailand is the only country that has not been colonized. Thailand has become a strategic buffer zone between Britain and France in Indo-China Peninsula by skillfully using the contradictions among various forces and balancing strategies, thus saving the country from extinction. In World War II, Thailand adopted the strategy of forming an alliance with Japan. When the Pacific War broke out, Thailand declared war on Britain and America. After Japan's defeat, Thailand declared its declaration of war against Britain and the United States invalid and was recognized by the United States. Thailand once again avoided the fate of a defeated country, became the only close ally of the United States in Indochina Peninsula, and enjoyed the status of "the main ally outside NATO".

1893 10, the Bangkok dynasty was forced to sign the Siam Treaty with France, which allocated Laos territory on the east bank of the Mekong River to France and paid France 3 million francs in compensation. At this time, France occupied a comparative advantage-an alliance with Russia.

It can be seen that there are some main reasons because Thailand is not necessary to be colonized. Originally, this country was small and there was no need to occupy it. If there are no resources around, those powerful countries will leave it alone. Even though Thailand was not colonized, it signed many unequal treaties and suffered great economic losses.
