The Cabinet Intelligence and Research Office has warned government offices before the new state secrecy law takes effect Wednesday that people who have studied or worked abroad have a higher risk of leaking secrets.

According to the 2011 documents obtained at the request of Kyodo News, the Cabinet Secretariat, the office that will supervise the controversial law with tougher penalties for leaking state secrets, pointed to the need to check educational and employment records in examining which public servants are deemed eligible to handle sensitive information.

Under the secrecy law, which was enacted in December last year, civil servants and others who leak sensitive information on foreign policy, defense, counterterrorism and counterespionage face up to 10 years in prison.
