The tourism ministry said yesterday that it was throwing the doors open to tourists from the four countries because they are already a good market, have strong interest in the Olympics and pose a low security risk.
"These tourists will boost the country's economy by spending in hotels, restaurants, car hire, travel agencies and many other sectors," Tourism Minister Henrique Eduardo Alves said in a statement.
"In this period, our attractions will be on global view. If we do our part, many of these tourists will return after the Olympics bringing friends and relatives," he said.
