A World of Warcraft expansion pack has received approval from China's Ministry of Culture, giving the game government clearance so that it can be played in the country.

The ministry approved "Wrath of the Lich King" last Friday according to one of the regulators websites. This follows last month's approval of the expansion by the country's General Administration of Press and Publication (GAPP).

Late last year both regulatory agencies were caught in a dispute over who had the authority to approve the previous World of Warcraft expansion "The Burning Crusade." At one point, the game was threatened with a shutdown order. But the latest expansion pack has passed the Chinese regulators without any apparent conflict.

NetEase, the Chinese online game provider for World of Warcraft, is planning a formal announcement about the expansion pack soon, said the company's investors relations manager Liddy Li.

"We have always been preparing for its release, but there has been no formal announcement yet," she said.
