Hong Kong-listed Tencent Holdings Limited, China's biggest instant message service provider, said yesterday its first half revenue more than doubled year on year, led by growth in its Internet value-added services like online games and voice chat.

But shares of Tencent fell yesterday as the company said it expects enforcement of China Mobile's tougher measures on its service providers will hurt its wireless value-added services, resulting in reduced growth of subscriptions and a loss of existing customers. Its shares fell 2.31 percent yesterday to HK$16.90.

First half revenues rose by 112.9 percent from a year earlier to 1.350 billion yuan. Net profits hit 517.6 million yuan, a year-on-year increase of 82.3 percent.
