China's largest auto parts maker got court approval on Tuesday for its controversial purchase of A123 Systems Inc, a bankrupt maker of electric car batteries, but the judge said he was troubled that a U.
S. rival might be working to kill the deal.
A123, which was partly funded with U.S. government money, was sold at an auction on Saturday for $256.6 million to Wanxiang Group of China, which outbid Johnson Controls Inc of Milwaukee.
The auction result prompted outcry from U.S. politicians who objected to A123's taxpayer-financed lithium-ion technology ending up in the hands of an economic rival. Johnson Controls has said it remains interested in A123 if Wanxiang fails to get approval from the U.S. government, which is coming under pressure to block the deal.
