Correct Answer:
B. Vietnam
Explanation:
The correct answer is Vietnam because Vietnam held the rotating ASEAN Chairmanship for the year 2020 and successfully transitioned the summits to virtual teleconferencing due to the global COVID-19 pandemic.
- Vietnam: This is the correct choice. As the official 2020 ASEAN Chair, Vietnam hosted both the 36th and 37th ASEAN Summits, alongside specialized emergency meetings, using secure video link architectures managed from Hanoi to keep regional policy active during global travel shutdowns.
- Incorrect Options:
- Singapore: This is incorrect. Singapore previously hosted the annual summit meetings in 2018 but acted as a participant rather than the host nation during the 2020 virtual sessions.
- Thailand: This is incorrect. Thailand hosted the physical summit iterations back in 2019 before formally handing over the chairmanship mallet to Vietnam for the 2020 calendar year.
- Indonesia (Modified Option 4): This is incorrect. Indonesia hosted the summit events later in 2023. Note that the original duplicated option 'Vietnam' was swapped to Indonesia to provide four unique choices.
