To what extent can a country criminalize acts outside its territory?
<p>Indonesia prohibits pornography.</p>
<p>If someone creates porn in Indonesia, that's illegal.</p>
<p>What about if an Indonesian citizen creates porn somewhere else?</p>
<p>What about if a non-Indonesian is a porn star somewhere else and then becomes a tourist in Indonesia?</p>
<p>Another recent example is this</p>

<p>China criminalized criticizing the CCP government for all people in the world. Can they really do that? Are there other examples of such codes?</p>

<p>To the extent that the country's constitution allows the legislature to make a law with extraterritorial scope.</p>
<p>(Of course other countries may or may not cooperate with the enforcement of that law.)</p>
<p>There might be as many examples of laws intended to have extraterritorial scope as there are countries.</p>
