andy1307 writes "Xinhua, among others, quotes a Bloomberg report saying the Committee on Foreign Investments in the United States, or CFIUS, might block the sale of IBM's PC unit to Lenovo over national security concerns. CFIUS is made up of 11 U.S. agencies, including the Department of Justice, the Department of Homeland Security, and is chaired by the Treasury Department. They are concerned Lenovo employees might be used to conduct industrial espionage. The Bloomberg story said members of CFIUS were focusing their attention on an IBM facility in North Carolina of the United States. The same article says IBM hasn't produced its own PCs for several years and that the bulk of its production is done by manufacturing partners, largely in China. In the past, CFIUS has blocked the sale of Global crossing to Hutchison Whampoa because it would have meant Chinese control of the undersea cable communication network."
