"The Asia-Pacific region cannot and should not relapse into the confrontation and division of the Cold War era."
Those comment have been interpreted in the Australian media as a reference to recent efforts by the US and Australia to increase geo-political pressure on China in the Pacific region.
Xi also said the region should make sure to keep supply lines functioning and to continue liberalizing trade and investment.
"China will remain firm in advancing reform and opening up so as to add impetus to economic development," he said.

Meanwhile, Prime Minister Ardern welcomed delegates and expressed regret that they couldn't be here in person.
"I wish I was welcoming you to the beautiful city of sails that is Auckland. But I shall do that instead in 2022, as we reconnect with the world," she said.
Ardern talked about New Zealand's pandemic experience saying the "lesson is that the health of our people and the health of our economies are intrinsically linked.
"New Zealand's economy is bouncing back, in fact, it has held up incredibly well throughout."
"Despite the tough picture internationally. Despite the challenges with supply chains. And despite the twin blows associated with the loss of two of our biggest export earners – tourism and international education. We have had strong economic growth."
Employment was at a record high and the third highest in the OECD, and we had one of the lowest levels of government debt in the OECD.
"And while it's been incredibly tough for many, business confidence has been sustained and companies continue to invest."

Apec organisers have stuck with plans for the event today and tomorrow, with the venue at Auckland's Aotea Centre effectively becoming a live broadcast studio for the fully virtual event.
The CEO Summit is separate event to the main APEC leaders Summit.
