Toyota Motor Corp. said Monday it is aiming for a global market share of about 15 percent by the early part of the decade beginning in 2010.

At the release of its 2010 Global Vision long-term management plan, Japan's largest automaker said it will work to expand its customer base and the worldwide appeal of automobiles.

Toyota said it will review its approach to global tieups to strengthen the competitiveness of its core engine and platform technologies, and will promote strategic technical alliances, including mergers and acquisitions, if necessary.
