The South Korean government is moving to clamp down on the illegal trade of drugs particularly through the Internet and social networking services.

The government released on Tuesday a set of measures to root out narcotics offenses, such as by analyzing X-ray results of express cargo items in real time. A comprehensive portal system will be established for customs officials to share information simultaneously. An agent and a detection dog will be stationed at international airports and harbors.

According to the Supreme Prosecutors’ Office, a total of 11,916 drug offenders were caught in 2015, a 29.9 percent increase from four years earlier. The amount of confiscated drugs also increased, to 93.6 kilograms last year from 76.4 kilograms in 2013.
