Hopes for open campuses and ¡°travel bubbles¡± this summer ¨C and possibly for the upcoming academic year ¨C have burst in east and South-east Asia, regions once lauded for their success during the pandemic.

In the past few days, governments from Taiwan to Thailand have tightened controls, causing universities to scramble with new closure announcements.

While many countries are reporting only scores or hundreds of Covid cases per day, this is still a marked increase. They are facing new Asian variants from places like?India?and many still have low vaccination rates.

Taiwan, one of the few places in the world to have avoided mass university closures thus far in the pandemic, has introduced its first major restrictions since spring 2020. ?

Similar arrangements impacting classes, dormitories, cafeterias and sporting events have been announced at National Tsing Hua University, National Yang Ming Chiao Tung University, National Taiwan Normal University and National Chengchi University.

Japan has been battling its most recent wave for a month. In April, the University of Tokyo announced further ¡°infection prevention measures¡±, in line with the government calling a state of emergency in some parts of Japan.

The latest rise in infections means that borders?are unlikely to open up in mainland China and Japan. Travel bans to those areas have been in place for a year, despite vocal criticism by some international students.

Meanwhile, the Chinese University of Hong Kong has become the first institution in the city to impose vaccine-related rules that, unlike?in the US,?have been uncommon in Asia.

Starting in September, students at residential colleges will need to be tested every 14 days at their own expense. One college has said vaccinated students will be prioritised for room availability, which is?usually competitive.

Malaysia has?already said?that it will be closing campuses for the next month.?
