Leaders of Asia-Pacific economies were unable to agree on communiqué at a summit in Papua New Guinea on Sunday as deep divisions between the United States and China over trade and investment dominated the meeting.
"You know the two big giants in the room," Papua New Guinea (PNG) Prime Minister Peter ONeill said at a closing news conference, when asked which members of the Asia-Pacific Economic Cooperation (APEC) group could not agree.
When asked about the main issues preventing agreement, ONeill replied: "The World Trade Organisation and reform of the World Trade Organisation," but said that was outside APECs remit.
"APEC has got no charter over World Trade Organisation, that is a fact. Those matters can be raised at the World Trade Organisation."
A Leaders Declaration has been issued after every annual APEC leaders meeting since the first in 1993, the groups website shows.
ONeill said as APEC host, he would release a Chairmans Statement later on Sunday.
Competition between the United States and China over the Pacific was also thrown into focus at the meeting in Papua New Guinea with Western allies launching a coordinated response to Chinas Belt and Road programme, promising to jointly fund a $1.7 billion electrification and internet project in PNG.Tonga, on the other hand, signed up to the Belt and Road and won deferment on a Chinese loan, a Tongan official said.
US Vice President Mike Pence, as he left the PNG capital of Port Moresby, listed US differences with China, a day after he directly criticised its Belt and Road programme.
"They begin with trade practices, with tariffs and quotas, forced technology transfers, the theft of intellectual property. It goes beyond that to freedom of navigation in the seas, concerns about human rights," Pence told reporters travelling with him.
PNG Foreign Minister Rimbink Pato earlier told Reuters that the multilateral trade system was the sticking point in drafting the communiqué.
Pato also confirmed to Reuters that Chinese officials had see him on Saturday over the communiqué, adding they were refused because they had not made "necessary arrangements" for a meeting, but denied media reports they had barged into his office.
At a Pacific Islands Forum in September, there was a similar dispute when Chinas envoy demanded to be allowed to address the forum before the prime minister of Tuvalu.
