President Rodrigo Duterte's colorful language was in full swing on Friday as he hammered the European Union again on Friday for allegedly threatening to cut aid.

Duterte, in a press conference in Davao City following his state visits to Brunei and China, said the E.U. threatened to cut aid and assistance to the Philippines if he fails to account for those killed in his war against drugs.

'P********!' Ganyang kaliit ang tingin n'yo sa amin?"

(Son of a b*tch. Is that how low you think of us?)

"Assistance, U.S. aid, you can go to hell. E.U., no wonder you are in shambles now. You cannot even agree to be together or not. Whether to form still a European community or disintegrate. Why? because all your lawyers are all stupid and idiots," Duterte said.

The E.U and the United States have criticized the extra-judicial killings and human rights abuses linked to the Duterte administration's war on illegal drugs.

The European Parliament urged the Philippine government to put an end to alleged extra-judicial executions in police operations and killings by vigilante groups.

The E.U. also urged the Philippine government to launch an immediate investigation into the killings and adopt "specific, comprehensive policies and programs," in full compliance with national and international obligations and respect for human rights.
