Macau's gangland war has prompted Australia to warn its citizens about the risks of travelling to the enclave. The Department of Foreign Affairs and Trade in Canberra yesterday urged Australians to 'exercise due care and maintain a high level of personal security' if they visited Macau. Last night, the enclave's tourist chiefs reacted angrily to the warning, describing it as 'inappropriate and unjustified'. A spokesman for the Macau Government Tourist Office said it would register its displeasure through 'appropriate channels'. The enclave joins more than 50 trouble spots around the globe - including Bosnia, Lebanon and Rwanda - which are listed by the Australian authorities as having varying degrees of danger. In the first four months of this year, gangland battles have claimed 15 lives in Macau. 'At this stage the Department of Foreign Affairs and Trade does not consider it necessary that Australians defer travel, but intending visitors should keep themselves informed of developments,' the advice read. The warning came as the secretary-general of the World Tourism Organisation, Francesco Frangialli, in Macau for a tourism conference, described the enclave as a safe and secure destination. Canada has stopped short of issuing a warning but has sent out an information sheet on Macau which refers to 'rivalry between criminal gangs' and reminds visitors to 'remain vigilant'.
