MANILA (Reuters) - Philippine President Rodrigo Duterte on Tuesday said his country, a longtime U.S. ally, was seeking to build "many news alliances" and could turn to Russia and China for help, including on tackling his country's drug problem.

"By next year, I will have entered into so many new alliances," he said during a speech after inspecting an illegal amphetamine factory.

He also said he would not allow his country's former colonial power, the United States, to "impose on us anything".

Though he said he wanted to be friends with China, he also said it was important it control the activity of drug criminals supplying narcotics to the Philippines.

"If you consider us your friend and want to help us, most of the materials are from China, what does that mean?," he said.
