"That required the US and Japan to agree, however there is nothing stopping the other 11 members now talking about what they might do without the US."
He said government ministers started conversations to that end in Peru last week at the Asia-Pacific Economic Cooperation (Apec) meeting.
Apec, which has 21 members including China, is the primary forum for economic growth and co-operation in the Asia-Pacific Region.
"You would have seen some reports coming out on how China is very keen to see how they could be involved in a deal around the Asia-Pacific.
"This is the beast we always talked about - if the US withdraws then they will hand influence in the Asia-Pacific to China."
He said China had long promoted the Asia-Pacific Trade Agreement, which it actively promoted in Peru.
"They have been promoting that for some time now and when TPP was progressing all of us in the Asia-Pacific wanted to do that option first.
"Something will come out of the Asia-Pacific region which New Zealand will be a part of. It just won't include the US for now and China will likely be at the centre of it."
