President Tony Tan Keng Yam met his Austrian counterpart, Dr Heinz Fischer, on Sunday in Germany, the President's Office said in a statement yesterday.
They met in Lindau where they were attending the 66th Lindau Nobel Laureate Meetings.
Dr Tan, who is on a six-day working visit to Germany, is attending the meetings in his capacity as a member of the Honorary Senate of the Lindau Nobel Laureate Meetings Foundation.
The foundation supports science and research, especially in fields for which Nobel prizes are awarded.
During the meeting, Dr Tan and Dr Fischer discussed Britain's referendum last Thursday, when a majority of voters chose to leave the European Union. They also exchanged views on other regional and international developments.
Both leaders also affirmed the warm bilateral ties between Singapore and Austria, and explored how relations can be further strengthened, the statement said.
This year is the 50th anniversary of diplomatic ties between Singapore and Austria.
While in Germany, Dr Tan also met senior officials of Deutsche Bank and Deutsche Bundesbank, Germany's central bank.
He hosted a reception in Frankfurt for more than 200 Singaporeans living in Germany.
Dr Tan returns home today.
