Lego will build its first toy factory in China to supply a regional market that is expected to be the world’s largest by 2016, The Wall Street Journal reported. Sales in the Danish company’s plastic bricks climbed 50% in Asia last year. The factory will supply up to 80% of the demand for the toy in Asia after it is completed in 2017. Other toy companies such as Toys “R” Us have turned their sights toward China to meet the growing demand for educational toys from Asian parents. China’s toy market was worth US$8.89 billion last year, up 18% on 2011.
