"North Korea, a top priority in the international agenda, increasingly poses new levels of threat of a grave nature to international peace and stability and the non-proliferation regime through its repeated and ongoing breaches of international law," the club of industrialised democracies said in a statement at the end of a two-day summit here.
"North Korea must immediately and fully comply with all relevant UN Security Council Resolutions (UNSCRs) and abandon all nuclear and ballistic missile programs in a complete, verifiable and irreversible manner.
The section of the statement dealing with Pyongyang concluded with a reference to the plight of mainly Japanese citizens kidnapped by the North Korean regime and held, in some cases, for decades.
"We urge North Korea to address humanitarian and human rights concerns, including the immediate resolution of the abductions issue."
Japanese Prime Minister Shinzo Abe and US President Donald Trump spent most of an hour-long meeting on Friday discussing tensions on the Korean peninsula.
