Diasporas can be a double-edged sword. You may recall that Canada was asked to be the mediator of choice in the Sri Lankan conflict back in the late 1990s. One of the reasons we didn't become involved was because the government at the time felt it was too contentious domestically to be engaged, even though we were then the largest development donor of assistance to Sri Lanka, which is why they turned to us.
