British Prime Minister David Cameron was to arrive in Japan late Tuesday for a two-day visit, hoping to strengthen the two countries' cooperation in the defence industry. "There are many opportunities for defence cooperation" between Britain and Japan, Cameron was quoted by Kyodo News as saying. "I hope to discuss these issues with Prime Minister (Yoshihiko) Noda so that we can pave the way for our defence ministers to agree more formal cooperation when they next meet," Cameron said. During his stay, Cameron was also to meet with Emperor Akihito and business leaders, according to a report of DPA.
