"We are highly confident that based on the evidence,data and analysis,Australia has an incredibly strong case to mount in relation to defending the integrity,and proprietary of our grain growers and barley producers,"Senator Birmingham said.
"WTO dispute resolution processes are not perfect,and they take longer than would be ideal,but ultimately,it is the right avenue for Australia to take at this point in time."
China's Foreign Ministry on Tuesday night said any measures it had taken were in line with its regulations and international practices.
"They are also responsible steps to safeguard the interests of domestic industries and consumers,"ministry spokesman Wang Wenbin said.
"We hope that the Australian side will reflect upon its own conduct,match its words with deeds,and provide favourable conditions for bilateral practical cooperation in various fields,instead of the opposite."
The dispute has been characterised by vague threats and sudden trade restrictions on different sectors since Australia called for a coronavirus inquiry in April.
In recent weeks the Morrison government,frustrated by a shutdown in ministerial communication from Beijing,has increasingly been referring to the perception of economic coercion created by China's"discriminatory actions".
Senator Birmingham on Wednesday went further and described the trade strikes as sanctions. He warned it would turn other countries off doing business with China,which remains Australia's largest trading partner,accounting for more than $150 billion in exports each year.
"The fact that China has accumulated a series of decisions that look like sanctions against
Australia,obviously changes that risk proposition for Australian businesses and industries as they choose to consider doing business with China,"he said.
"It also has a knock-on effect in relation to others around the world."

Senator Birmingham said Australia had no intention of changing its position on human rights,Huawei,the coronavirus inquiry,nationals security or foreign investment decisions.
"We are right to stand by our values which include the principles of supporting China's economic prosperity,which has achieved the miracle of our lifetime and lifting hundreds of millions out of poverty and improving living standards for many as a result,"he said.
"Ultimately what is going to be required here from Australia,a period of calm,consistency and patience and for China,we hope,to be willing to come to the table."
The press conference is likely to be one of the last for Senator Birmingham after more than two years as trade minister ahead of a cabinet reshuffle this week. The South Australian senator will move full-time to the Finance Ministry.
Education Minister Dan Tehan and Employment Minister Michaelia Cash are the leading candidates to take on the trade portfolio.
