EDMONTON, Alberta — Canada’s oil-rich province of Alberta is banning wine imports from neighboring British Columbia over a dispute about a proposed pipeline.

Alberta Premier Rachel Notley announced Tuesday that the province is banning wine from British Columbia wineries effective immediately.

Last week, British Columbia’s government announced it is looking at rules to limit any increase in imports of petroleum from Alberta’s oil sands until an independent panel can better analyze whether the system is safe and if it can adequately deal with a spill disaster.

The rules could kill the proposed Trans Mountain pipeline expansion that would move oil from Alberta to the Pacific coast.

The wine ban is the second trade retaliation that Notley has announced. Last week, she suspended talks to buy electricity from British Columbia.
