This is recycled news. They've been saying this for years. However trade continues in dollars because a) importers and exporters find it simpler to deal in the US currency and b) in order to get access to renminbi you have to get LCs for the whole amount while in most cases traders are used to underinvoicing and remitting payments through alternative channels. So it's just not going to happen. I'm guessing they've recycled this news now because IK has nothing to show for his visit to China and they need a win for PR purposes.
