Prime Minister Scott Morrison is still confident the US and China can bring about a timely end to their trade dispute.
US President Donald Trump said on Friday he wasn't sure the issues could be resolved before the next presidential election, in November 2020.
Mr Morrison said if a deal was delayed that long Australia would address the economic implications in the government's mid-year budget update and next May's budget.
"We had a discussion about that yesterday and I've obviously urged that the sooner we can get to an outcome on that (the better)," he told reporters in Washington on Saturday.
"I don't think there's any delay there. It's just there's a lot of issues to deal with and we'll continue to encourage them to get to an outcome."
He said he got a clear sense from Mr Trump during their meeting that he was continuing to pursue the deal with China.
Labor frontbencher Joel Fitzgibbon suggested Australia could play more of an intermediary role between the two economic giants.
"That's a very very complex challenge and we need to get that balance right, and I'm not sure Scott Morrison has that balance right at this point in time," he told Sky News.
Mr Trump told reporters on Friday he was looking for a complete deal not a partial one.
"I don't think I need it before the election. I think people know that we are doing a great job," he said.
While the prime minister has been feted at the highest levels in the American capital, he has yet to receive an invitation to Beijing.
But he insisted that was "not something that's overly vexing us", saying the relationship with China was on good enough terms.
He pointed out he catches up with President Xi Jinping regularly at international summits and Australian ministers have had recent meetings with their counterparts, including Trade Minister Simon Birmingham travelling to Beijing in early August.
