China people in Laos mainly participate in:

1, hydropower and other engineering construction; Planting such as rubber trees; Copper mines, potash mines and other mining industries (these are some colonial practices that are called by the West to destroy the environment and plunder natural resources).

2. Redwood, rosewood, etc. It was purchased, roughed and exported back to China to make furniture (because Laos' policy is becoming stricter, it involves smuggling).

3. Cars, motorcycles, mobile phones, luggage, hardware and machinery, small commodities, food, etc. They are all sold, but the quality is generally not high (giving people the impression of selling inferior goods).

4. Restaurants and other catering industries in China.

That's basically it. If you want to do business, you'd better check it out yourself.
