China's Dongfeng Motor is studying the "rationality" of coming to the aid of troubled French automaker PSA Peugeot Citroen, AFP reports citing a top Dongfeng official. Dongfeng, China's second-biggest carmaker, has been rumoured for months to be in talks with Peugeot about a potential capital injection into the struggling firm. The two companies already have a joint venture in China. "We are discussing the rationality of the project," Dongfeng Motor Corp. General Manager Zhu Fushou told reporters on the sidelines of an industry conference in Shanghai. Speaking at the conference earlier, Zhu touched briefly on the issue, saying Dongfeng would have to see "advantages" in any deal. "Not only PSA but also for other targets, if we can reach a consensus that it has complementary advantages, we might do it. On the other hand, if we can't see this, we won't do it," he said. "As a cooperative partner (of Peugeot) we are extremely concerned about its overall earnings situation," he added.
