HANOI, Vietnam (AP) — Coca-Cola and Samsung have pulled their advertising from a popular Vietnamese website notorious for providing unlicensed downloads of Western and local songs, in a rare victory against online piracy in a country where it has grown unchecked.

The companies abandoned Zing.vn after The Associated Press alerted them to local and international concerns about the website, which is the sixth-most visited in the nation of 87 million people.
