With repeal of mandatory country-of-origin meat labeling part of the spending bill making its way through Congress Friday, Canadian officials are pleased, however, that doesn’t mean they won’t stop retaliation efforts just yet. Agri-Pulse reported Thursday that Canadian trade officials vowed not to stop their efforts until the repeal is signed by the president. Trade officials from Canada and Mexico were scheduled to meet with the World Trade Organization Friday to receive final authorization for retaliatory tariffs. WTO could authorize the tariffs effective immediately, before a bill could be signed. Canada’s ag minister said earlier this week he was “cautiously optimistic this will lead to a resolution,” but added “the bottom line is it must be repealed or we will retaliate.” Senate Agriculture Committee Chairman Pat Roberts of Kansas said Thursday he thought Canada and Mexico may hold off on immediate retaliatory action due to congressional efforts to repeal the law, adding “They know that we are trying to do our best.”
