The House of Commons Defence Committee has published a report: Rash or Rational? North Korea and the threat it poses which analyses sanctions adopted in response to North Korea’s nuclear programme.
The report states that North Korea’s nuclear weapons testing began in 2006, and that UN sanctions have been imposed in 9 increasingly severe UNSC resolutions (the latest being in December 2017, see here). Countries “traditionally supportive” of North Korea, such as China and Russia had approved all 9 resolutions, and some imposed additional measures (including the US and the EU). The report concludes that the “inadequate enforcement of sanctions” and “lax enforcement on the part of certain countries”, has “significantly limited their impact on North Korea’s economy”. It recommends that the FCO should “set out what steps it has taken to encourage other countries to enforce – in full – the agreed sanctions against North Korea”.
