US regulator fights Chinese Aixtron buyout

US regulators are yet again set to block a takeover of a European technology company by a Chinese buyer, a further sign of how China Inc.’s recent shopping binge is raising security concerns in the Western world, according to The Wall Street Journal.  German technology firm Aixtron SE late Friday said it was informed by the powerful Committee on Foreign Investment in the US, or CFIUS, about “unresolved U.S. national security concerns regarding the proposed transaction.” The news comes after Germany’s economics ministry late last month withdrew its earlier approval and reopened a review of the 670 million Euro ($710 million) acquisition of Aixtron by Grand Chip Investment GmbH, the German unit of China’s Fujian Grand Chip Investment Fund LP.
