I sincerely doubt this represents an immediate threat to US space interests. Lets face it, China can hate us all they want, but they're economically dependent on us, like it or not. This feels more like something to put in the face of the Indians and Japanese. Nations immediately bordering China, with various conflicting interests with China, that might not be so ruthless in response to an orbital attack.
