You summed it up well.
I think the approach has to be collective, similar to dealing with tax avoidance by multinational corporations. There's the U.S., of course. If Canada goes it alone, there are two risks. First, Canadian investment in China doesn't represent a lot. It's a lot to us, but it's not a lot to the Chinese. In addition, generally speaking, this could encourage some Canadian companies to relocate, so they could carry on business as usual somewhere else, without having to meet certain requirements. There is a risk of tax evasion, or even a risk of the company moving out of Canada if the bulk of its operations are based outside the country. Take the mining sector, where that's very often the case. Under Canada's special regime, Canadian mining companies with almost no Canadian operations are still registered in Canada for tax and legal reasons.
There is a risk, so I think the best approach is to work collectively with our partners to promote new practices. A long time ago, the UN Global Compact was launched. It's an honour-based initiative that brought together companies pledging to respect and strengthen human rights. It has yet to produce results.
You're right, there are no easy solutions. We can condemn abuses, but it's a hard problem to manage.
