MANILA - President Rodrigo Duterte on Tuesday said he is working to ensure that the Philippines won't have to rely on international allies.

Speaking to the Philippine Marines in Fort Bonifacio, Duterte said he will work to make the country survive on its own.

"Please understand. This republic will rise. This Republic of the Philippines will continue to be great. Sabi ko, darating ang panahon, hindi na natin sila kailangan lahat. We will survive on our own. We will fight our wars on our own, and we will win as a country," Duterte said, referring to his statements against the U.S. government for criticizing his war on illegal drugs.

Duterte claimed that the U.S. government is undermining his administration.

"Ina-undermine tayo ng Amerikano ngayon. They're manipulating na ang peso raw bumaba. I would like to ask you to remain faithful to the republic," he said.

"Give me time so that I can go out of this ambit of our... kinakaya kaya kasi tayo ng Amerikano eh. Binastos na ba. There's always China, and I talked to Medvedev, the premier sa (ASEAN Summit)," Duterte added.

Duterte reiterated that he can ask China and Russia for help if the U.S. continues to criticize him.

"Kapag inipit nila ako, I will have alliances, new alliances of commerce and trade. I'll be visiting China and maybe, Russia," he said.

Duterte earlier announced a plan to seek closer economic ties with China and Russia, even as the Philippine peso hit a seven-year low and foreign investors pulled out of the Philippine stock market which analysts say is connected to growing concern over Duterte’s unpredictability.
