(Bloomberg) -- Hassan Rouhani paid the first visit by an Iranian president to
Japan in 19 years, just as the U.S. strengthens enforcement of its
sanctions in a standoff over nuclear development.Japan, which is walking a tightrope between its tradition of friendly ties with
Iran and reliance on the U.S. as a military ally, is keeping the visit low key. Formerly one of Iran’s biggest customers, Japan hasn’t imported any oil from the country since May, according to government and ship-tracking data.President Donald Trump’s administration is seeking to step up enforcement of Iran sanctions by increasing pressure on global shippers, Chinese state-owned enterprises and exporters of raw materials used in metals production, U.S. officials told Bloomberg this week.Since Trump withdrew from the Iran
nuclear deal in 2018, Tehran has refused to buckle to
American demands for a more comprehensive agreement and has moved forward with efforts to enrich uranium. Japanese Prime Minister
Shinzo Abe has tried to ease tensions, including by making the first visit to Iran by a sitting Japanese premier in 40 years.Abe told Rouhani he was very concerned about rising tensions in the
Middle East and urged him to stick to the terms of the nuclear agreement. Through an interpreter, Rouhani criticized the U.S. for withdrawing from the deal.The two leaders didn’t hold a joint press conference, and the Rouhani was back in Tehran by Saturday evening after being in Japan for less than 24 hours.Upon his return Rouhani said that the Japanese government had offered a “new proposal” on the issue of “breaking sanctions,” and that Iran presented its own plan for countering the penalties. Negotiations in Tokyo lasted several hours and both countries planned to continue their talks on the subject of sanctions, he said.“We had very substantial discussions and negotiated for maybe three to four hours last night,” Rouhani said in a statement to reporters upon his arrival in Tehran, which was shown on state TV. He also welcomed a decision by Japan, conveyed during his visit, not to join the U.S.-led naval coalition in the Persian Gulf.Abe was expected to explain Japan’s plans to dispatch a Self-Defense Forces unit, which will include a vessel, to the Middle East on an intelligence-gathering mission, according to documents distributed by the Foreign Ministry ahead of the meeting.(Updates with Rouhani comments in Tehran from seventh paragraph.)\--With assistance from Aaron Clark and Ramsey Al-Rikabi.To contact the reporters on this story: Isabel Reynolds in Tokyo at ireynolds1@bloomberg.net;Emi Nobuhiro in Tokyo at enobuhiro@bloomberg.netTo contact the editors responsible for this story: Brendan Scott at bscott66@bloomberg.net, Shamim Adam, Ros KrasnyFor more articles like this, please visit us at bloomberg.com©2019 Bloomberg L.P.
