In my opinion, there is a big difference between the two.
In order to build relations with China, China has asked for recognition that Taiwan is an integral part of China. Mr. Mitchell Sharp said this was impossible, because Taiwan is not part of China.
The fact that China is asking Canada to recognize this is already evidence. China has not asked Canada to recognize that Shandong is part of China and Canada has not asked China to recognize that Alberta is part of Canada.
If one does not dispute the claims, it is because one wants to have a relationship with China. If one does not accept the recommendations, it is because it is an established fact that Taiwan is not part of China. So one cannot support China's position.
