Canadian lumber company Transpac Group confirmed on Mar. 13 that it’s largely shutting down its site on Afognak Island near Kodiak, effective immediately. Representatives of the company say that’s because earlier this month, China halted imports of U.S. logs in response to tariffs President Donald Trump imposed on Chinese goods.

China’s exports to developing markets have soared, opening indirect routes to the U.S. market that officials in Beijing worry may be closed under pressure from President Trump.
