IP Dragon's blogroll is updated. See 'Treaties (in force)' on your right hand side. Now it includes all IP treaties of WIPO and WTO (and UN's Vienna Treaty Convention crucial for the interpretation of treaties) which China has acceded to or at least signed. What is remarkable is that China has already signed the WIPO Trademark Law Treaty (TLT) in 1994 but has not ratified it. Is it because the newer treaties have made this one obsolete? If you know why, please tell me (ipdragon at gmail dot com).
For WIPO's one glance overview of China's ratifications and signatures, see here.
