As of April 1, 2022, Malaysia will reopen to tourists. Only people who are fully vaccinated against the corona virus are allowed to enter the country. Furthermore, a negative PCR test must be submitted.
The finding must not be older than 48 hours at the time of crossing the border. Furthermore, you have to have an antigen rapid test carried out at an official test center within 24 hours of entering the country. But you don't have to go into quarantine.
Prime Minister Ismail Sabri explained, among other things, that the forthcoming relaxation of entry regulations will boost tourism and thus the economy. Malaysia had largely sealed itself off for around two years. Non-citizens could only enter with a valid reason.
