SAP Corp expects a US$1 billion revenue in China in 2015 and the Chinese market to become one of its top five regional markets in the "middle term" amid increased investment and huge demand, SAP said at the close of an IT show yesterday.

"China is the most exciting and strategic market for SAP," Alex Atzberger, SAP's senior vice president, said in a interview during the Mobile Asia Expo in Shanghai.

In 2015, China is set to account for 5 percent of SAP's global revenue which may hit US$20 billion. Over the mid-term, China will become one of the top five regional markets by revenue for SAP which added that over the past years the growth in Chinese revenue was always "double digits" annually.

The Germany-based enterprise software giant is also seeking to tap prospects in convergence of mobility and management as well as huge-volume data analysis, Atzberger who is also head of SAP's Fast Growth Markets and China Growth Plan, said.

SAP also said it would invest US$2 billion in China under a five-year plan until 2015.
