China's Tencent has taken a $50 million stake in Kik Interactive, an investment that values the Canadian mobile messaging company at more than $1 billion, Kik said on Wednesday.

Kik, a Waterloo, Ontario-based company whose chat platform is popular with U.S. teens, has long said it aims to emulate the success of Tencent's WeChat, which has expanded from messaging to facilitating commerce in China.
