Thailand became a vassal state of China in the Ming Dynasty and was occupied by Britain in the late Qing Dynasty. Thailand was called Siam in ancient times. Some ancestors originally lived in Yunnan, China, and moved south to Indo-China Peninsula to avoid the invasion of Mongols. During this period, Xishuangbanna has been engaged in intermarriage and trade with Rana and other parts of northern Thailand. 1238, Sukhothai Kingdom was established.

The main ethnic group in Thailand is Thais, accounting for 75%, and the second largest ethnic group is Chinese, accounting for 14% of the total population. In ancient Siam, Thailand, China immigrants actively participated in the local political, economic and cultural construction, which had a great influence. Zheng Xin, a native of Chaoshan, Guangdong, even established a dynasty that annexed Wu Li, and was later called the first of the five emperors in Tai Huang.

A vassal state in Ming and Qing dynasties

1, Vietnam, which had been under the jurisdiction of China before the Song Dynasty, became independent, but the Qing Dynasty paid tribute to China, and became independent after the Sino-French War. In fact, Vietnam is the most stable country in the tribute system of Ming and Qing Dynasties. In addition, it is originally the territory of China, so the cultures of China and Viet Nam are very similar. Chinese characters have long been used in Vietnam, and many Vietnamese history books are written in Chinese. Now many Vietnamese educators also advocate learning more Chinese.

2. Korea. The Han Dynasty established four Han counties in Korea. Goguryeo and Baekje were destroyed in the Tang Dynasty. Silla pays tribute to China. Later dynasties paid tribute to China. In the Qing Dynasty, China and Japan declared independence in the Sino-Japanese War of 1894-1895, and then became independent. In a small area in the south of the Korean peninsula, there are three small tribes: Mahan, Chen Han and Han Ge, collectively known as Koreans. Of course, the coexistence of Han 4 counties only lasted for more than 20 years. In 82 BC, Zhao Di, Emperor Wu of the Han Dynasty, merged the eastern and southern parts of Fan Zhen, Lintao County and Xuantu County into Le Lang County, and the county administration was still in Pyongyang, the capital of North Korea.

3. Ryukyu (now Okinawa Prefecture) was a tribute of China in the Ming Dynasty and was annexed by Japan after the Qing Dynasty. In the early years of Hongwu in the Ming Dynasty, envoys from Shannan, Shanbei and Zhongshan of Ryukyu Island came to Nanjing with gifts, that is, salted fish and kelp, expressing their willingness to surrender to Daming. At that time, Zhu Yuanzhang had just won the world, and when he saw foreigners coming to North Korea, he was flattered. So he waved his hand and asked the Ministry of Industry to carve three gold seals and give them to the kings of the three countries respectively, thus completing the relationship between the suzerain and the vassal state.
