McDonald's will increase its investment in China by 40% and open 175 to 200 new stores in the country in 2011 and 1,000 stores by 2013, McDonald's China CEO Zeng Qishan said Wednesday.Half of the new openings by 2013 will be drive thru stores, which currently account for 10% of the Golden Arches' total restaurants in China. The number of drive thru stores are expected to reach 550 by 2013, Zeng said. KFC, its bitter foe, has less than 70 drive thru stores in the country.
