to deter refugees from crossing. This aspect of Chinese border control policy has been criticised by human rights organisations. Cyprus: As a result of Northern Cyprus's sovereignty dispute with Southern Cyprus, the South (a member of the European Union) has imposed restrictions on the North's airports, and pressure from the European Union has resulted in all countries other than Turkey recognising the South's ability to impose a border shutdown on the North, thus negating the right to self determination of the predominantly Turkish Northern Cypriot population and subjecting their airports to border controls imposed by the predominantly Greek South.

Israel: Border control, both on entry and on exit, at Israeli airports rate passengers' potential threat to security using factors including nationality, ethnicity, and race.

Separation of families seeking asylum: In April 2018, as part of its "zero tolerance" policy, the American government ordered the separation of the children of refugees and asylum seekers from their parents. As a consequence of popular outrage, and criticism from
