President Ferdinand "Bongbong" Marcos Jr.'s unannounced trip to Singapore over the weekend had been "productive," Press Secretary Trixie Cruz Angeles said early Monday morning.

"Naging produktibo ang pagdalaw sa Singpore ni Pangulong Ferdinand Romualdez Marcos Jr. Pinagpatibay niya ang mga pangunahing usapan sa huling state visit sa bayan na ito, at pinatuloy ang paghihikayat sa pag invest sa bayang Pilipinas," Angeles wrote in a social media post.

The Press Secretary also shared a social media post by Singaporean Minister for Manpower and Second Minister for Trade and Industry Tan See Leng where the latter shared a photo of the Filipino leader with some Singaporean officials at the Marina Bay Street Circuit for the Grand Prix.

Tan, in his post, said he was "happy to meet" various heads of state, including Marcos, at the Grand Prix, where they had the opportunity to discuss their bilateral relationships.

"Happy to meet various Heads of States, Ministers and foreign dignitaries (including Bongbong Marcos, President Surangel Whipps Jr., Cambodia's Minister attached to the Prime Minister and Managing Director of Electricite Du Cambodge (EDC), Keo Rottanak, Cambodia's Minister of Commerce, Pan Sorasak, Advisor to the Royal Court, Kingdom of Saudi Arabia, Dr. Fahad Bin Abdullah Toonsi) to affirm our bilateral economic relationships and strengthen collaborations in energy cooperation as well as exchange views on manpower policies on the sidelines of the race," Tan said.

Marcos made the trip to Singapore days after he ended his six-day working visit to New York, United States of America.

His trip had not been announced nor confirmed by the Malacañang even when photos of the President in the event made rounds online.

The Singapore F1 Grand Prix was canceled for the past two years due to the ongoing global health crisis.

Mexican Formula One driver Sergio Perez of Red Bull Racing won the Singapore Grand Prix on Sunday.
