Boris Johnson: We must increase pressure on North Korea over missile tests
Foreign Secretary Boris Johnson has said Britain stands "shoulder to shoulder" with Japan in efforts to put an end to North Korea's nuclear and missile tests.
He said in Tokyo on Friday that "we all need to increase the pressure on Pyongyang through diplomacy and sanctions, and that must include China using its influence to bring North Korea back to the negotiation table".
Mr Johnson is meeting Japanese Prime Minister Shinzo Abe, the foreign minister and the governor of Tokyo on day two of a three-day trip to Japan.
The Japanese foreign ministry says they are discussing increased diplomatic and security co-operation and the Olympics.
Mr Johnson called North Korea's recent launch of its first intercontinental ballistic missile "a reckless provocation".
