NetEase Inc, a major Internet portal operator in China, plans to invest heavily in mobile Web services, said a senior company official, as companies are rushing to secure a position in the rising sector.

William Ding, NetEase's chief executive officer and director, said the first half of the year will see the launch of a full portfolio of mobile Internet services.

The company has offered a number of services for mobile devices for some time, including a dictionary, news and a note-taking application, as an increasing number of people turn to mobile devices to access the Web.
