HANOI, Vietnam (AP) — A record company that accuses a Vietnamese entertainment portal of making its songs available for free download has filed suit in an American court against a U.S technology and media firm which invested in the website.

Lang Van, which is based in California, is seeking millions in damages for alleged copyright infringement.

The complaint filed last week points to a possible vulnerability for venture capital funds looking to tap into Asia’s Internet industry.

The suit was filed on behalf of Lang Van against Massachusetts-based technology and media company International Data Group, its venture capital arm in Vietnam and VNG, the Vietnamese company that owns and operates Zing.vn, the entertainment portal accused of being a pirate site.

IDG Vietnam invested in VNG in 2005.
