US President Barack Obama is poised to block the sale of German chip equipment maker Aixtron (AIXGn. DE) to China's Fujian Grand Chip Investment Fund (FGC), Bloomberg reported, citing sources. In November, Aixtron said that the CFIUS told the company it would recommend that its pending takeover by Fujian be blocked. The deal, announced in May, valued Aixtron at 670 million euros ($715.56 million). Aixtron and Fujian Grand Chip Investment Fund could not be immediately reached by Reuters for comment.
