It was no secret that A123 Systems (NASD:AONE) was desperate for money. It's also no secret that Chinese companies are interested in buying Western companies, especially when they can acquire useful technology in the deal. So the announcement that Wanxiang Group Corporation, a Chinese largest autoparts manufacturer which has significant U.S. operations, had signed a non-binding memorandum of understanding to invest up to $450 million in A123 through a combination of bridge loans, convertible notes, and warrants seems like good news for both companies.
