Trade Minister Tim Groser is promising fresh trade talks with China if its new trade deal with Australia is better than the agreement with New Zealand that took effect in 2008.
Mr Groser says if Australia has been given a better agricultural deal he will take up the issue with Beijing.
Canberra's agreement means most Australian dairy products will not be subject to safeguards that apply to New Zealand exports, where a tariff is applied when a quota is reached. The ABC reports only whole milk powder is expected to have the safeguards applied in the Australian deal.
Under this country's deal, if China secures a better arrangement with another country, it must match that with New Zealand.
Mr Groser told Morning Report he would address this situation with China.
"Unquestionably we would have a discussion with the Chinese authorities in due course on that point.
"I don't really think we're going to do this during this week with the Chinese president's visit - this has to start off at a lower level than head of government."
Australia and China have signed a Declaration of Intent - a framework for a free-trade agreement - six years after New Zealand's deal with China took effect in October 2008.
The ABC has quoted Federal Trade Minister Andrew Robb as saying the provisions for dairy products in $A18 billion deal is better than in New Zealand's deal.
If the agreement goes through, all tariffs on Australia's dairy products going into China will be lifted within 11 years.

A reporter for ABC Rural, Lucy Barbour, said the 15 percent tariff on Australian infant milk formula will be phased out within four years.
She said liquid milk would be tariff-free in nine years and there were moves to eliminate tariffs on cheese, yoghurt and butter over the same timeframe.
"Andrew Robb said this deal would be equal to New Zealand's and as far as dairy goes it is a better deal," she said
Ms Barbour said the National Farmers' Federation, Australia's key farming lobby group, had been lobbying for a deal for some time and it was delighted and "nothing but pleased".
"It is something that I am sure New Zealand farmers will be very keen to see how it plays out.
"I think the interesting thing to watch will be how farmers in the Australian sector capitalise on this deal and actually make the most of it."
NZ still 'best' dairy supplier
A New Zealand agriculture academic said Australia's potential free trade deal with China will be about the same as New Zealand's in the long run.
Jacqueline Rowarth, an agri-business professor at the University of Waikato, said New Zealand will still be a good supplier.
"I think they are just taking competition a little too far ... they're clearly feeling vulnerable," she said.
"We can still do it more efficiently, we do have water that comes out of the sky - this is not the case in Australia at all times of the year. New Zealand is still the best place to do grass-fed dairy production."
Professor Rowarth said Australia also had hot temperatures that cows do not like and its deal might only be a better one for a short time.
"What we can remember with China is they're building up their own supply and they have got caveats, or checks and reviews at various stages - so at any stage things could change."
