I know Korea was interested in the past. I don't know whether they've moved on at this point to seek it from others.
These conversations come up, and I'm fortunate, being in Ottawa, that I'm regularly invited to speak with foreign diplomats here. The message they constantly receive is that this isn't something Canada wants to explore.
How many times do they ask and get rebuffed before they move on to others who are happy to sell to them? I couldn't say.
