Siemens Enterprise Communications, a major provider of unified communications equipment systems, vows to double its market share in the next three years in China's market, which is rapidly growing yet sees increasingly intensifying competition, a top company official said Tuesday.

"We have already about 7 percent market share in the unified communications market in China. In the next three years, we have an objective to double the business here," Wolfram Fischer, general manager of Siemens Enterprise Communications in Asia-Pacific, told the Global Times in an exclusive interview.

Unified communications generally refers to a set of technologies and organizational practices that integrate different forms of communications like phone, video and Web conferencing.

China's rapidly growing market for unified communications spurred Siemens Enterprise Communications to mull over expansion plan in the country, Fischer said.

Revenue from unified commutations and the collaboration market in China is expected to increase to $732.3 million in 2014 from $336.4 million in 2010, at a 17.5 percent compound annual growth rate, according to global market research firm IDC.

Apart from big cities like Beijing, Shanghai and Guangzhou, Siemens plans to cover more second- and third-tier cities with emerging opportunities, according to Udi Baran, CEO of Siemens Business Communication Systems Ltd in Shanghai.

Siemens opened a new office in Southwest China's Chongqing last month. In addition to increase the number of local partners in the next few years, Siemens also plans to provide more localized technology for the Chinese market as part of their expansion strategy, Fischer said.
