Mitsubishi Motors Corp. is negotiating with DaimlerChrysler AG about a comprehensive alliance that would give the world's fifth-largest automaker an equity stake in the Japanese carmaker, sources said Tuesday.

DaimlerChrysler may acquire a 30 percent stake in MMC, and the Japanese carmaker in turn purchase a stake in DaimlerChrysler, the sources said.

Although the two companies hope to reach an agreement by the end of the month, it is still possible the deal might collapse, they said.
