Burma and Laos are working with China to help curb gambling by Chinese citizens.
News reports say local police are helping to screen customers at Burmese casinos near the border with China, to keep Chinese people from entering. Chinese troops also are reported guarding the national border in certain areas to keep would-be gamblers from crossing into Burma.
The reports say the crackdown has had a big effect on the economies of gambling towns near the Chinese border. About 80 gambling venues have been shut down in Burma and neighboring Laos since the crackdown began at least six months ago.
Local governments have aided the crackdown by cutting off power, telecommunications and transportation to some casinos.
