China and North Korea.

China and North Korea have a similar way of selecting leaders. Both countries have a one-party system, with the Communist Party of China in China and the Workers' Party of Korea in North Korea. The leaders are chosen through a combination of party appointments and internal party processes, rather than through a direct democratic election.
