Cayetano, however, said he is still against inviting Special Rapporteur on extrajudicial, summary or arbitrary executions Agnes Callamard to the country, as she has prejudged the country's human rights situatuation and has called President Rodrigo Duterte a murderer.
"Throughout the three cycles of the Universal Periodic Review, and most especially during the Duterte regime's participation in the process, the Philippines has exhibited a total mockery of global human rights mechanisms, with the government's blatant distortion of facts on extrajudicial killings and human rights violations in the country, its record of using the United Nations as a platform to justify its crimes against the Filipino people, and its doubletalk on compliance to human rights instruments. Now, aside from these episodes of, I said, sad incidents, overall, I think the Americans also redeemed themselves a lot", the President added.
"As host country, we hope to make the event productive and pleasant to our foreign guests", the presidential spokesperson said.
"President Trump will definitely receive a very warm welcome in Manila", Cayetano said after the White House confirmed last Friday the USA chief executive's participation in the East Asian Summit.
Trump will travel between November 3 to 14.
Cayetano added Duterte is looking forward to welcoming Trump in Manila.
During the Asia tour, Trump would not be stopping over in "good friend" India which the White House has categorised as falling into the Pacific region.
President Donald Trump will grace the 31st Association of Southeast Asian Nations (Asean) Summit and Related Meetings that will be held in the Philippines in November, Malacañang confirmed on Saturday.
This will be his first trip to Asia as a President.
During a visit to Asean's Jakarta headquarters in April, Vice-President Mike Pence had promised allies - anxious about waning United States engagement in the region - that Mr Trump would attend the bloc's summit in Manila this November.
"President Trump will discuss the importance of a free and open Indo-Pacific region to America's prosperity and security", the White House said in a statement. "The president's engagements will strengthen the worldwide resolve to confront the North Korean threat and ensure the complete, verifiable and irreversible denuclearization of the Korean Peninsula".
VIDEO: At the UN General Assembly, Donald Trump warned that the USA will be forced to "totally destroy" North Korea unless Pyongyang backs down from its nuclear challenge, mocking North Korean leader Kim Jong Un as a "rocket man" on a suicide mission. It is expected that the trip will be dominated by the North Korea nuclear threat.
"While rattling sabers, Mr. Trump for the moment has stuck to a strategy of increasing economic pressure and strengthening regional solidarity".
