In the latest move to operationalize the Anglo-Japan Alliance, the Yomiuri English Language site (Japan News) reports :
Japan and Britain are making arrangements to hold joint surveillance activities between November and December to look out for illegal ship-to-ship transfers by North Korea
The joint operation will be conducted within the framework of the UN command, rear (in Japan), which has remained active since the armistice of the Korean war in 1953.
The surveillance will be conducted by Royal Navy frigate HMS Argyll, the third UK Warship to sail in the region and visit Japan this year.
