The laws of a country either protect or prohibit certain activities. One country might protect specific activities (e.g. free speech, peaceful assembly, freedom of religion) while another country prohibits them. As a result, the two countries will have different cultures.
The same is true of companies. One might promote trust, respect and integrity while another does not. It’s easy to see how cultures will differ. In all cases, the cultures result from the “laws” in place – the written and unwritten policies.
If you want a different culture, simply change the rules.
