Toyota Motor Corp on Wednesday promoted more foreigners to senior posts, including the first woman and first African-American to hold executive titles, diversifying a management team long dominated by Japanese men. The world’s biggest automaker appointed Europe chief Didier Leroy to become one of six executive vice presidents (EVP) effective after the company’s annual shareholders’ meeting in June. He would be the first foreigner to become a Toyota EVP, the highest post to be held by a non-Japanese.
