The demonstration comes ahead of the leaders' planned bilateral talks on November 18, with protesters opposing Trump's visit and a US-backed technology initiative they fear could threaten Indigenous communities.

Police confronted demonstrators attempting to access roads near the summit venue as opposition to Washington's involvement in the Philippines grew.

Jerome Adonis, one of the protesters, delivered a direct message to the US president.

"The message of working people is very clear. Donald Trump , you are not welcome in the Philippines, out of the Philippines" says protester Jerome Adonis.

Much of the opposition centres on Pax Silica, a US supply-chain initiative aimed at reducing dependence on China for semiconductors and rare earths.

The programme includes a proposed 1,620-hectare AI manufacturing hub north of Manila, which protesters fear could displace Indigenous families.

The planned project has become a major point of contention ahead of Trump's meeting with Marcos, as demonstrators raise concerns about its potential impact on local communities.
