Protesters clashed with police in Manila on Thursday ahead of US President Donald Trump's visit to the Philippines as part of his five-nation tour of Asia.

The demonstrators, who included members of women's rights and economic trade groups, brandished anti-Trump posters and banners as they clashed violently with riot police.

President Trump is due to meet Philippine President Rodrigo Duterte.

The White House has indicated that Trump is unlikely to publicly chide him for overseeing a drug war with extrajudicial killings.

Phillipine President Rodrigo Duterte said Monday he could not stop Chinese men from fishing his country's exclusive economic zone in the disputed South China Sea.

In his annual state of the nation address, Duterte told congress the Phillipines would certainly lose in any clash over his country's exclusive economic zone, which is claimed by China.

"When Xi (Jinping, Chinese President) says I will fish, who can prevent him?" Duterte asked as he defended his non-confrontational approach to China over the territorial disputes.

"If I send my marines to drive away the Chinese fishermen, I guarantee you not one of them will come home alive," Duterte said, adding that diplomatic talks with Beijing have allowed the return of Filipinos to disputed fishing grounds where Chinese forces previously shooed them away.  

Critics have repeatedly criticised Duterte, who has nurtured friendly ties with Beijing, for not standing up to China's aggressive behaviour in the disputed waters and for deciding not to immediately seek Chinese compliance with an international arbitration ruling that invalidated Beijing historic claims to virtually the entire sea.

"Do you want war?" he asked.

The Philippines' long-simmering territorial rifts with China and Duterte's centerpiece campaign against illegal drugs and corruption were spotlighted in his speech.

The 74-year-old took office in June 2016 and has remained hugely popular in opinion polling despite drug war deaths that have sparked international alarm and other controversial policies.

More of his allies captured congressional seats in midterm elections in May, giving them a tighter grip on the legislature, especially in the 24-member Senate, which opposed some of his key legislative proposals last year, including reinstating the death penalty and amending the pro-democracy constitution.

More than 5,200 protesters rallied despite a downpour outside the House complex to call for Duterte's removal while a smaller number of pro-Duterte supporters rallied separately.

Protest leader Renato Reyes Jr said protesters were fighting to have Duterte's term cut short, adding "the killings are not stopping and he's going to go for more."

Left-wing protesters burned a mock Chinese flag and a giant mural with the images of Duterte, Xi and US President Donald Trump.

Military and police were placed on full alert and authorities declared a no-fly zone over the venue and outlying areas to ensure security.
