It's the same old game the USA is playing. Let the agreement expire make a half hearted effort at getting to talks, never mind extending the agreement. Next have the usual suspects shout "unfair" and let the government impose the countervailing duties, then drag the works all the way to the WTO, all the while collecting these duties. They have yet to win at the WTO, but know that it will really heave a big monkey wrench into the works. In short, it's the same monkey business as always, except Trump in the White House, with all his bull roar, won't help in the least.
As soon as the countervailing duties start stop all raw log exports to the USA, lets see if they find replacement lumber of that quality.
BTW in our household we buy as little with "Product of USA" designation as possible; works quite nicely, thank you!
