Facebook is reportedly looking to set up a sales office in China even though access to the social media site remains blocked in the country. The U.S. company plans to open the office within a year so it can work with local companies keen to advertise on a global platform, reported Bloomberg, which cited sources familiar with the issue. It added that Facebook was in discussions to rent office space in Fortune Financial Center, located in Beijing’s central business district, but remained undecided on whether to hire full-time staff or contractors to support the sales office.
