MANILA - President Rodrigo Duterte sang during the gala dinner for the 31st ASEAN Summit on Sunday, upon the request of US President Donald Trump.

In a tweet by Public Works Undersecretary and lawyer Karen Jimeno, who was in the gala dinner at the SMX Convention Center, Duterte is seen singing the OPM hit "Ikaw."

"Ladies and gentlemen, I sang uninvited, in a duet, with Miss Pilita Corales, upon the orders of the commander-in-chief of the United States," a smiling Duterte said after singing.

Trump arrived in the Philippines Sunday for meetings with his Southeast Asian counterparts, the last stop of his Asian tour.

The US President earlier offered to mediate between claimants to the South China Sea, where five countries contest China's sweeping claims to the busy waterway.

Foreign Affairs Secretary Alan Peter Cayetano thanked Trump for his offer but said that ASEAN countries will need to arrive at a consensus before taking the deal.
