Tencent's (0700) shares rose to their highest since 2021 after DeepSeek, the AI service that's shaken up the industry since its emergence this year, debuted on the big tech company's WeChat social media platform.

The shares closed nearly 4 percent higher in Hong Kong yesterday, outperforming the market index's 0.02 percent decline.

Shenzhen-based Tencent is integrating DeepSeek's artificial intelligence model into WeChat search, the company said in a statement.
