Speaking to CNN Philippines Monday, Presidential Spokesperson Harry Roque, who is part of the country's delegation to South Korea, said, "There were at least four agreements signed, but the cumulative total of investments to be brought home is 4.9 billion (pesos) and overseas development assistance is one billion doubled, which will go and assist the country in infrastructure such as roads and bridges".
The conservative newspaper Chosun Ilbo noted that South Korea's government indicated Duterte's visit is strictly business and sent the head of the Defense Acquisition Program Administration instead of a senior diplomat to welcome the Philippines president at the airport to send a clear message to that effect.
The president bussed one of the OFWs on the cheek, then gestured to the other that he wanted to kiss her on the lips.
The clearly nervous woman did not resist the kiss, which was broadcast live.
"Are you single? You're not separated from [your husband]?" Mr Duterte said, according to the Philippine Star.
During the appearance late Sunday in front of a mostly Filipino crowd, Duterte called the woman onstage and pointed to his lips.
"Don't take it seriously".
The left-wing Gabriela women's party condemned Duterte's act, which it said underscored his "machismo and misogyny". The Filipino president is well-known for past sexist and controversial remarks including jokes about rape and violence against women. This is despite the mother of two children saying she is married to a South Korean.
"I assure you, for me and even the President, there was no malice in the kiss", she said.
He leaned in and kissed her on the mouth. "It was not a meeting of two consenting individuals on equal terms". "Uneven power relations were clearly at play".
"Come here! Where's my (kiss)", Duterte said, instructing her to explain to her husband - after learning he was not among the audience - that they were engaging in a "joke".
Duterte critic Senator Leila de Lima is behind bars on charges she insists are politically motivated after battling with the president.
In a statement posted online, the Gabriela women's alliance said the kiss was a "disgusting theatrics of a misogynist president who feels entitled to demean, humiliate or disrespect women according to his whim".
