The Philippines' crime-fighting president says he plans to ask Chinese officials why some Chinese citizens who visit his country are involved in illegal drugs. President Rodrigo Duterte, who has vowed to end crimes within six months of taking office on June 30, also said late Sunday that he will not hesitate to grant pre-signed presidential pardons to law enforcers accused by human rights advocates of abusing their authority in cracking down on narcotics, as long as the soldiers and police involved do not fabricate evidence and tell the truth.

Duterte made the comments amid an outcry from human rights advocates about the deaths of at least 212 suspected drug traffickers in deadly confrontations with law enforcers since he won the May 9 presidential race.
