Senator Charles Schumer (D-NY) sent a letter July 27 to Treasury Secretary Timothy Geithner urging him to block China’s state-owned oil company, China National Offshore Oil Corporation, from acquiring Nexen Inc., a Canadian oil company, until China makes changes to its foreign investment and international trade policies. Senator Schumer called for China to join the World Trade Organization’s Government Procurement Agreement, bolster intellectual property rights enforcement, limit the scope of its foreign investment review policy to national security, and nullify its indigenous innovation policies, positing that as chairman of the Committee on Foreign Investment in the United States, Secretary Geithner could withhold approval of the transaction until China meets these conditions.
