The more immediate concern to smaller trading nations has to be the current US Administration's threat, real or implied, to the World Trade Organisation. For the first time Apec leaders have failed to agree on a communique from their meeting and the reason is said to be that the US wanted them to call for wholesale reform of the WTO.
China was not the only member to baulk at that demand. The host Prime Minister, PNG's Peter O'Neill, explained, "Apec has got no charter over the World Trade Organisation. That's a fact."
The Trump Administration believes China has failed to observe WTO rules since its admission to the organisation and accuses it of forced technology transfer and breaches of copyright. But rather than make the effort to help apply those rules, the US seems determined to emasculate the organisation and replace it with something more amenable to the doctrine of America First.
Meanwhile, the US suspects China harbours an ambition to rewrite global trade rules for its own purposes, a project which, if true, would be assisted by President Trump's withdrawal from the Trans-Pacific Partnership recently ratified by New Zealand and other Pacific Rim countries. China has been promoting a Regional Comprehensive Economic Partnership of 16 Asian countries.
Many an international exercise is being held back by US President Donald Trump's determination to renegotiate just about every agreement the US has made. The failure to agree on an Apec communique is not a disaster in itself, they are seldom ringing declarations of progress.
But at the very least a communique represents a willingness to work together towards something worthwhile. Even that seems beyond agreement when the US comes to lock horns with China, threaten it with more tariffs and keep America First.
