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 the U.S- venture capital firm which invested in the website, seeking millions in damages for copyright violations.

The complaint filed last week in Boston points to a possible vulnerability for venture capital funds looking to tap into Asia’s Internet industry. Some of the sites that generate the most traffic do so because of free song and movie downloads with little concern for intellectual property rights.
