A number of Chinese firms, including computing powerhouse Lenovo (0992.HK), are seeking to expand their investments in the US, the Wall Street Journal reported. Liu Chuanzhi, Lenovo’s chairman, said that he was looking to deepen his firm’s investments in the US. Liu also said that Lou Jiwei, chairman of sovereign wealth fund China Investment Corp (CIC), was interested in infrastructure projects in the US. The interest among key Chinese firms to invest in the US works nicely for the Obama administration, which is both keen to ameliorate the country’s stubbornly high unemployment rate and to build infrastructure capacity. However, US regulators can occasionally present problems for Chinese firms, such as when they blocked the attempt by Huawei to invest in a US telecom firm in 2010.
