Efforts by a Philippine agency to combat drug trafficking will be supported by the country's law enforcement officers, in a sign that the government is seeking to reinforce its anti-drug campaign.

Philippine police have been ordered by their president to rejoin the country's ongoing war on drugs.

Rodrigo Duterte's instructions "to resume providing active support" to the Philippine Drug Enforcement Agency indicate an about-face on his previous decisions related to the fight against narcotics.

The 160,000-strong police force in the Philippines apparently dwarfs the country's ant-drug agency, which currently numbers about 2,000 officers.

The country's anti-drug campaign kicked off on May 9, 2016 when Duterte won the presidential elections.
