The Philippines' ambassador to the U.S. said President Donald Trump will host his Philippine counterpart in the White House to discuss how the longtime treaty allies can further deepen their security and economic engagements and bolster deterrence against aggression in Asian security flashpoints.

Philippine President Ferdinand Marcos Jr will meet U.S. President Donald Trump in Washington this month, Manila's top diplomat said on Friday, with an increased trade tariff on one of Washington's top defence allies set to be discussed.

DFA Secretary Theresa Lazaro says the country has sent negotiators to the US to tackle the new duty rates on Philippine exports.
