"Certainly there is the potential for China to join the TPP,"Mr Turnbull said,noting he had"active discussions"with other leaders,including Japanese PM Shinzo Abe on Monday,about resuscitating the doomed trade agreement.
Stressing that Australians were more dependent on trade than Americans,the PM said other nations could"make whatever judgments they wish"but"Australian trade policy is written in Canberra in the interests of Australian jobs".
Mr Turnbull also held out hope the US might reconsider,noting past support from congressional Republicans and incoming Secretary of State Rex Tillerson.
"It is possible that US policy could change over time on this,as it has done on other trade deals,"he said.
Trade Minister Steve Ciobo would not declare the TPP dead - as the Labor opposition did on Tuesday - but acknowledged it could not proceed in its current form without the US.
"It's a great shame[but] it's not unexpected,"he told Sky News on Tuesday.
