North Korea relies on China for Internet connectivity, partly due to long-standing ties between the two nations. North Korea borders just three countries: South Korea, Russia and China. The Chinese Internet is well developed and the Russian border is far from Pyongyang, the North Korean capital. It’s unclear whether that link was used at all in cyberattacks that are blamed on North Korea. Other telecom links are just as meagre: North Korea doesn’t permit its citizens to make or receive international telephone calls.”]
