The Committee also noted that measures applied to international travellers such as testing, isolation, quarantine and vaccinations should be based on “risk assessments" to avoid "placing the financial burden" on international travellers.
UNWTO secretary general Zurab Pololikashvili said blanket travel restrictions "are simply counterproductive" when it comes to stopping the spread of new virus variants.
"In fact, by cutting the lifeline of tourism, these restrictions do more harm than good, especially in destinations reliant on international tourists for jobs, economic wellbeing and sustainable change," he added.
