AP, TOKYOJapanese Minister of Justice Masako Mori yesterday vowed to strengthen border departure checks and review bail conditions after Nissan’s former chairman, Carlos Ghosn, fled the country. Mori told reporters at a news conference the ministry has already acted to prevent a recurrence, but declined to give details. Ghosn skipped bail while awaiting trial on various financial misconduct allegations and later said from Lebanon that he did it to escape injustice. “Japan’s justice system allows investigating the facts while it ensures the individual basic human rights at the same time,” Mori told reporters at the ministry. Japan does not have an extradition treaty with Lebanon, but Mori left open the possibility Japan could seek Ghosn’s return.
