MANILA, Sept. 25 (Xinhua) -- Philippine President Rodrigo Duterte continued to enjoy high trust and approval ratings, according to an independent poll released on Tuesday.

A survey by Pulse Asia Inc. conducted from Sept. 1 to 7, showed 75 percent of the 1,800 Filipinos aged 18 and above surveyed nationwide approved of the way Duterte runs the country.

The survey further showed that 72 percent of those surveyed continue to trust the 73-year-old leader.

At the national level, Pulse Asia said Duterte experienced a 13-percentage points slip in his approval ratings compared to 88 percent approval rating he earned in June.

Duterte's spokesman Harry Roque said Duterte's ratings were still high. "We take note of the survey results but we are not affected by it," he told a news conference.

Duterte assumed the presidency in June 2016. He vowed to stamp out corruption and improve law and order in the Philippines by waging war against criminals and terrorists.
