President Ferdinand "Bongbong" Marcos Jr. is set to fly to Singapore on Tuesday morning for a two-day state visit.

The chief executive is expected to be welcomed by Singaporean President Halimah Yacob and Prime Minister Lee Hsien Loong in Singapore.

Press Secretary Trixie Cruz Angeles earlier said Marcos's itinerary includes a series of economic briefings, business forums, and meetings with potential foreign investors.

Meanwhile, Angeles said Marcos had a "very productive" state visit in Indonesia.

"It was very productive, extremely so because the President did not expect that the talks between him and [Indonesian] President [Joko] Widodo would progress so rapidly in such a short time," Angeles said in a press conference on Monday night in Jakarta.

The Philippine and Indonesian governments on Monday inked four agreements on defense and security, culture, and creative economy.
