"The Secretary will attend [in] May at Washington the Association of Southeast Asian Nations (ASEAN) Ministers Meeting.and meet with the US Secretary of State", Department of Foreign Affairs (DFA) spokesperson Robespierre L. Bolivar said at a press briefing on Wednesday.
But analyst Aaron L. Connelly of the Lowy Institute for International Policy said that, considering Mr. Trump's "habits", the U.S. leader is unlikely to attend the ASEAN summit in Manila.
Moreover, Trump would be gracing the event, European PPP Expertise Centre alias EPEC Summit scheduled to be held in Vietnam.
"Multilateral meetings of this sort, we usually expect 100% attendance. And numerous leaders who do not attend do so because they have internal issues and-which prevents them from coming", Paynor said.
Bolivar also said that chairing ASEAN has an "income generation aspect" in towns, cities, and provinces because around 150 global meetings will be held across the Philippines. In response, Duterte made several profanity-laced outbursts against Obama, his country's long-standing ally.
The 10 leaders will also meet at the Philippine International Convention Center (PICC) and will have a retreat at the Coconut Palace.

"Instead of helping us, the first to criticise is this State Department, so you can go to hell, Mr. Obama, you can go to hell", Duterte said during a speech a year ago.
Duterte also described Washington as an "unreliable ally", saying Filipino forces have not benefited from joint combat exercises with USA troops. "But he seems to be very busy", Duterte told reporters in Bohol.
The outspoken Filipino politician warned Obama against raising the issue of human rights with him when the two met, saying: "Son of a bitch, I will swear at you", but later apologised for the remark.
Paynor said the meeting with the Brunei leader will be held on April 28 and with the Indonesian leader on April 29.
"However, our administrative rules, including procurement laws made it very hard for us to prepare because bidding process usually takes all of three months", he said.More news: War sacrifice of Canadian soldiers praised
