Huawei Technologies, the world's No.2 telecom equipment maker and the sixth largest mobile phone vendor, posted a 33 percent rise in net profit in 2012, reversing a fall in 2011 thanks to new telecom projects and smartphone sales.

Privately held Huawei, which ranks behind Sweden's Ericsson in telecom equipment sales, reported an unaudited net profit of 15.4 billion ($2.5 billion), up from 11.6 billion yuan in 2011, Chief Financial Officer Cathy Meng said.
