World Trade Organisation (WTO) chief Roberto Azevedo has warned of a "clear risk" of a trade war sparked by protectionist policies.
The global community must be attentive because "the risk of a trade war is very clear", the WTO Director General said on Wednesday here at a trade forum.
Azevedo warned that whichever country applies unilateral measures, other countries would respond, triggering a domino effect.
"It is easy to see where such chain reactions begin...Should a trade war break out, countries will, in the end, be worse off than when the dispute begins," he said.
Azevedo also called for more dialogues, noting the potential influence that digital technologies can have on world trade.
He said new technologies are growing faster than traditional sectors like exports.
"We need to raise awareness among leaders and governments that we are willing to work with them to identify solutions ... for these types of phenomenon," said Azevedo, adding his agency was promoting relevant dialogues with officials and international organisations.
The WTO's annual report, to be released in September, will shed light on the trend and the importance of training the work force so it can take advantage of the new opportunities, he added.
