HONG KONG, Dec 6 (Reuters) - Apple Inc’s chief executive Tim Cook said on Wednesday he sees Tencent Holdings , China’s biggest social network and gaming company, as a great partner and thinks very highly of its founder Pony Ma.

Cook also told the Fortune Forum in Guangzhou that he couldn’t be happier with how the iPhone X is doing in China.

China is Apple’s third-largest region by sales, but it has lost market share in recent years as consumers switch to local rivals.
