Taiwan is not officially a UN member and can therefore not be a part of the UN human rights treaty system. However, it has chosen to create a parallel human rights system, adopting each of the major human rights treaties into domestic law and establishing a process of regular review, analysis, recommendation and improvement.
In this regard it has recently completed the 2nd cycle of reporting under the Convention on the Elimination of all Forms of Discrimination Against Women (CEDAW). The news was recently reported in the Taiwan Today News. The next steps will include a formal review hearing in June of this year, followed by recommendations of the reviewing panel, and implementation of the recommendations.
More information on the report is also addressed in the official government press release announcing the publication of the report, although regrettably a copy of the report itself does not appear to be available yet. It would be helpful if a government website were established to report and monitor Taiwan's treaty implementation efforts in this regard.
