"This suggests that the position of US about of the issue is that "This land is yours" is debatable." Fair point. The wording is intentionally vague and up for interpretation - because as you say, we all know US's opinion is that China is China, and Taiwan is Taiwan, but in order to avoid pissing off China, we keep things as ambiguous and vague as we can. Strategic obfuscation, if you will.
