Travel bubbles, also known as travel corridors and corona corridors, are essentially an exclusive partnership between two or more countries/territories that have demonstrated considerable success in containing and combating the Covid-19 pandemic within their respective borders.
Vietnam stopped all international commercial flights in March 2020. International visitors entering the country since are mainly experts, high-tech workers, investors and foreigners working on national projects.
The country has been successful in containing its outbreaks with strict quarantine and tracking measures, having gone over a month without community transmissions. The government is also working on a 'vaccine passport' scheme to reopen its door to foreign tourists.
However, the Vietnamese government is calling for more vigilance against Covid-19 amid intensified outbreaks linked to new variants in neighboring countries like Cambodia, Laos and Thailand.
Taiwan has been widely applauded for its management of the pandemic, with one of the lowest per capita Covid-19 rates in the world, with 1,110 infections and 12 deaths so far.
