The legacy of this for jurisdictional control continues to the modern day. Cassel writes, "extraterritoriality has left many policy-makers in mainland China with a legacy of deeply felt suspicions toward international law, international organisations, and more recently, human rights". With part of its legitimacy resting on claims to strengthening national sovereignty and territorial integrity, the Constitution of the People's Republic of China explicitly states that foreigners must abide by PRC law. And the PRC government claims the right, under article 10 of its criminal code, to prosecute Chinese citizens for crimes against the criminal code which are committed abroad, even if already punished for the crime. These emerge from significant claims of the importance of national sovereignty, a reaction to its abridgement in the past, where almost no nations emphasise the importance of their sovereignty more than China does today.
