Mr Wong also met his Indonesian counterpart Sri Mulyani Indrawati, who chaired the meeting, and congratulated Indonesia on its successful conclusion.
“Singapore is honoured to have been invited. It was a good opportunity to meet so many familiar faces (and some new ones) after so long,” he wrote on Facebook.
On Wednesday, Mr Wong also met several of his counterparts from the Asia-Pacific, as well as beyond.
They included Malaysian Finance Minister Tengku Zafrul Aziz, Indian Finance Minister Nirmala Sitharaman, Japanese Finance Minister Shunichi Suzuki, and Philippine Finance Secretary Carlos Dominguez.
Mr Wong met Luxembourg’s Finance Minister Yuriko Backes for the first time, and said they discussed areas of mutual cooperation.
He also met Turkey’s new Finance Minister Nureddin Nebati, and Brazil’s Minister of the Economy Paulo Guedes.
“Brazil has a highly developed digital finance market and an energy mix that is 85 per cent renewable. Much more that Brazil and Singapore can do together,” Mr Wong wrote.
