Do I need a visa on arrival to go from Thailand to Laos and back?

If a Chinese citizen returns to China from Laos, he does not need a visa. Regulations on the Entry and Exit Administration of Chinese Citizens stipulate that Chinese citizens can freely enter and exit China's borders with a valid Chinese passport. Therefore, if Chinese citizens hold a valid Chinese passport, they do not need a visa to return to China from Laos. However, it should be noted that due to the impact of the COVID-19 epidemic, there may be certain entry restrictions and epidemic prevention measures. Please keep abreast of local entry policies and requirements, and make health declarations and epidemic prevention measures. If you are a non-Chinese citizen returning to China from Laos, you need to apply for a visa based on your own circumstances.
