International tourism is set to fall by 70% this year, marking the sector's biggest slump since records began in the 1950s, United Nations World Tourism Organization (UNWTO) Secretary-General Zurab Pololikashvili told newspaper Handelsblatt.
He said this prediction for the coronavirus-hit sector was based on the assumption that countries around the world would gradually open their borders from August.
