Trump was in Manila attending the Association of Southeast Asian Nations summit, which began with an opening ceremony and photo op of attending world leaders. The heads of state were invited on stage to participate in the conference's traditional ASEAN group handshake, in which each leader crosses their arms and joins opposite hands with the leaders next to them.

After some effort and grimacing, Trump smiled as he successfully executed this traditional handshake.
