The 2020 IISS Shangri-La Dialogue (SLD) would be untenable as no one can say how long countries will close their borders in response to the rapidly evolving COVID-19 situation. Even if delegates can get to Singapore when airline flights have dried up - some military delegations have flown to Singapore using their own aircraft in the past - defence ministers and armed forces chiefs are likely to be heavily engaged in their home nation's efforts to fight the virus. Defence chiefs many not be able to spare a weekend in Singapore, bearing in mind the travel time and the expected quarantine period upon returning home.
