I think it would have a very negative effect. The use of the concept of reciprocity in trade negotiations was an effective technique in order to get barriers to come down. To use that same technique to get at investment barriers, I think, would be a very effective way to shoot yourself in the foot, because the issue is not the nationality of capital but the acquisition of capital.
In almost all instances, capital does not have a nationality. So if we're interested in developing this country--and I don't care whether it's a natural resource or a manufacturing or service part of the economy--then we will need capital. If that capital is not readily available for a particular venture in this country, then we should welcome it from any other investors who are prepared to risk that capital.
