Two days later, he will host Trump and other world leaders at the Association of Southeast Asian Nations, or ASEAN, summit, with a 50th-anniversary gala.
A likeness of President Duterte peeked out from behind the figure, as the two leaders sat down for formal talks less than three kilometres away.
Overly amicable talks between Trump and Putin would be an awkward sell for the White House as it denies any wrongdoing.
Regardless of whether Trump directly praises Duterte's programme, or says nothing about it at all, his mere presence will be interpreted as a signal to law enforcement there, in the United States, and elsewhere that corruption and criminal violence in the service of a policy goal is acceptable.

Asean and China also highlighted the role of witnesses in identifying and prosecuting corruptors and said they would develop "an effective protection system for witnesses in corruption cases, where appropriate". "I don't care about human rights, believe me".
In particular, this was due to the Trump administration's explicit and conscious decision to prioritise strategic cooperation with Asian allies over promotion of human rights and democracy values.
