To ans U Q, I really don't know.
To what I heard : They might turn that area to be a China Town.
They said:"There are alot of Chinese living around the stadium"

According to my source had reported : There are about 1.5 mil chinese living in Laos. True or Not I really have no clue.
Its locate at Km18 known as Dump site.

Well, have the stadiums is better than No stadium.
Chinese little better than Vietnamesey(bad anyway)

To what I had seen, I guess the Laos government had known idea what to do with over populating Vietnamese living in Laos(est:2-2.5mil) so they had to invited the chinese into Laos for many reasons.

Do you know Chinese and Vietnamese they don't get along.
They are both Communist but crash each other during 1979.
