Mr Wyatt had two meetings in Beijing with the International Department of the CPC,which fosters links between the Chinese regime and political parties around the world.
These meetings included a"working talk"with vice-minister Xu Lyuping and a"welcoming luncheon"hosted by director-general Ma Hui.
"It is my understanding that all financial contributions to the trip were made by the Australian Guangdong Chamber of Commerce,"Mr Wyatt said.
However,he said the CPC"assists with facilitating a number of delegations between China and Australia".
China experts havedescribed the International Department as"a crucial vehicle for advancing China’s modernisation goals,studying current international conditions,and fostering ties with influential foreigners from every region".
Mr Wyatt said he had never met with Mr Huang or anyone who identified themselves as a representative of his businesses.
When asked byFairfax Media why he accepted the trip he said:"It is important to take opportunities to visit and build relationships with our state's strongest economic partner."
"In every trip I have made to China I have met with either government officials (local,provincial or Central) and/or representatives from the relevant level of the Chinese Communist Party,"he said.
Mr Bowen said the trip was organised as a young leaders'dialogue as part of a"mutual exchange"between the Communist Party's Central Committee and other political parties,including the Australian Labor Party.
"Mr Wyatt is correct that I suggested he join the delegation,primarily due to the importance of the China trading relationship to the Western Australian economy,"he said.
The Australian Guangdong Chamber of Commerce and Mr Huang did not respond to requests for comment.
