That all seems very logical to me, and you use scientific data to prove things to that country, which needs our legumes.
You are experts and you are surrounded by other experts. Why doesn't India accept your arguments? I assume that this is not the first time you have tried to show them this. Why is it taking that country so long to accept it? India is a trade partner that is far from Canada, and this is not clear. Why would it now accept what it would not accept six months ago?
