In an interview with Xinhua, Professor Dominic Dwyer from University of Sydney reviewed the Wuhan trip, which he called complex but fruitful. "It was a very complex process, but all in all we had a very successful review of a lot of literature and a lot of data. Quite a number of conclusions and recommendations that were agreed to by both sides were made. I think it puts together the framework for further work to sort out the origins of this pandemic," he said.
