North Korea’s support for Russia has resulted in Vladimir Putin having a debt to repay to Kim Jong-un - a terrifying prospect given the country’s ongoing ballistic missile tests.
While the US has a strong stance on the tests and would like the United Nations to punish the North with more severe sanctions for all intercontinental ballistic missiles launched, Russian President Putin could get in the way of this, International Relations expert Donald Kirk said.
Mr Kirk suspects Kim could play up his strong relationship with Putin to ensure Russia blocks any move.
