Within the past week, several Chinese spouses of Taiwanese have stirred up controversy by advocating on social media for China to invade Taiwan. However, that kind of language does not fall under freedom of speech and expression as defined in the UN’s International Covenant on Civil and Political Rights (ICCPR).
Under Article 20 of the covenant, war propaganda and encouragement of national, racial or religious hatred that constitutes incitement to discrimination, hostility or violence are prohibited. That is a major exception to the general protections and stipulations listed in the preceding article, which states that everyone has the right to hold opinions without interference.
