Both are unacceptable
China's saying of Japan has no right to patrol SCS=US demanding China to stop building islands.
I think that in the case of the US statement, it was not nearly as unequivocal. The US statement, "urged," China to stop.
The actual wording was:
US Statement said:
"We urge China to stop its land reclamation program, and engage in diplomatic initiatives to encourage all sides to restrain themselves in these sorts of activities."
This wording is not nearly as strong or inflexible as what is being reported from the Chinese General.
It seems to me that when he uses the terms "unacceptable," or "not welcome," that it is more in the form of a demand and is far less flexible. To state that any Japanese patrols are "unacceptable," and that the Japanese are "unwelcome," implies that the Chinese will not allow it.
Either way, it is not up to China to tell other sovereign nations who is or is not in international waters, and more than it would be for the US to "tell," China to cease its improvements.
But, IMHO, that is not what the US did. The US did not say that it was unacceptable, it simply urged China to consider stopping, and to open up more dialog instead.
Had the Chinese made a similar plea...urging Japan not to patrol, and wanting to open up a dialog, I believe that would have been easier to consider..
Perhaps there is an improper interpretation or translation of what was actually said.
Probably an imaginary one, conjured up by NBC itself.
Maybe, Engineer, but when NBC goes to the following length to identify him:
NBC said:
Major General Zhu Chenghu, a professor of strategic studies at China's National Defense University
...somehow I do not think it is "conjured up."...we will have to wait and see how the PRC responds.
Clearly, if such clear and specific identification is "conjured up," the PRC will be quick to tell us so.
