Background: I write for a magazine issued by a lumber industry trade association. We seek to educate the public on matters affecting our industry, both in the U.S. and abroad. As a major trading partner, anything involving the lumber trade in China potentially affects us and our readers.
Request: I need a report on China's ban on the import of lumber from Australia, which started in 2020.  I am particularly interested in the reasons for the ban, including both the stated reasons and any available speculation or information about unstated reasons for the ban.  My particular focus is on Chinese lumber imports from the Australian states of New South Wales and Western Australia, but information about bans on Australian lumber generally would also be useful.
