CITIC Pacific has agreed to sell its 50 percent non-controlling interest in Guoan for 3.5 billion yuan ($543 million), a move to allow it to focus on three major business lines, special steel making, iron ore mining and property development in China, the company said in a statement to the Hong Kong stock exchange late on Friday.

CITIC Guoan holds interests in cable TV, system integration and software development in China, and has a 41.42 percent interest in Shenzhen-listed Guoan Information.

Separately, CITIC Pacific also said in a release on Friday it expected delays in production and export of iron ore from its Western Australia project to the first half of 2012 from the end of 2011.
