What rubbish! Given our population is about .015% of China, one might expect they will be fairly obvious. China is huge and if you think they should just be quiet and buy our iron ore you are not real.
Our national sovereignty is not at risk but the importance and presence of such a giant is a fact that people may just have to get used to.
