Vietnam is finally allowing residents to gamble in select casinos—a scheme aimed at opening up the lucrative industry, although analysts warn that casinos located in border cities may have to take the brunt of the government’s pilot program.

“We would expect many to struggle to survive over the duration of the three-year Vietnam locals pilot program,” Union Gaming analyst Grant Govertsen said in a note.

Last week, the Vietnamese government announced it would allow citizens over 21 years old to play in local casinos from mid-March, as long as they have a monthly income of at least VND10 million (USD445).

“After three years… the government will decide whether to continue Vietnamese people’s access to casinos,” the government said in a statement.
