Boten is China on Laotian territory

Boten ist the borderline from Laos to Yunnan in China. But when you come to Boten, everything seems like being in China. Only Chinese money, the Yuan is accepted at the market, most of the scriptures only are in Chinese, almost all cars have Chinese license plates, the spoken language is Mandarin and even the clock goes the Chinese time and not the time from Vientiane.
China has leased very big Laotian northern territories for the next 30 years with an option to extent the leasehold an other 30 years.
Laotian citizen who aren't employed by Chinese companies generally are displaced from own territories.
