Top Aixtron shareholder says German govt review of takeover 'irresponsible'

LONDON (Reuters) - The biggest shareholder in German semiconductor manufacturing equipment maker Aixtron , Argonaut Capital, said the government's plan to review an agreed takeover by Chinese investment fund Fujian Grand Chip was "irresponsible". Argonaut's chief exeuctive, Barry Norris, said the reopening of a review into the deal, announced Monday and linked by Fujian Grand Chip to concerns over defense technology, was based on "highly dubious allegations" and driven by domestic German politics. [nL8N1CV0TY] Norris said the "protectionist posturing over Chinese investment would seem utterly irresponsible for Aixtron's stakeholders... and set an alarmingly arbitrary precedent for future government interference in EU financial markets."
