Britain would be less attractive to Japanese investors if it left the European Union, Japanese Prime Minister Shinzo Abe said on Thursday.
Leaving the EU "would make the UK less attractive as a destination for Japanese investment," Abe said at a joint press conference following talks with British Prime Minister David Cameron in London.
Abe joins several foreign leaders, including US President Barack Obama and Chinese President Xi Jinping, who have backed Cameron's campaign for Britain to remain in the EU after a referendum on June 23.
Obama was criticized by Leave campaigners last month after he warned that a vote to leave the EU could put Britain "at the back of the queue" for negotiating a bilateral trade deal with the United States, as Washington prioritizes an agreement with the EU.
Speaking at Thursday's press conference with Abe, Cameron said Japanese investment "matters enormously to the prosperity of the UK," totalling 38 billion pounds (55 billion dollars) in 2014.
"Japanese firms see Britain as the gateway to Europe," Cameron said. "That’s why more than 1,300 Japanese companies have a presence here in the UK, employing more than 140,000 people."
