Japan has stepped up sanctions against Iran over its nuclear program. The additional sanctions include a freeze on the assets of those linked to nuclear development and tighter supervision of financial transactions.
Japanese investment in energy development projects in Iran will also be restricted. Among other sanctions, Japan said it would effectively ban new energy-related investment by not providing medium to long-term export credit commitments for trade with Iran.
But resource-poor Japan did not impose any restrictions on oil from the country, which accounts for 10 percent of its crude imports. The fresh sanctions follow tough measures against Iran announced last month in a UN Security Council resolution.
Yoshito Sengoku, Japanese Chief Cabinet Secretary, said, "These new sanctions come in addition to what was decided in the Security Council resolution. We believed it was necessary in order to prevent the proliferation and making of nuclear arms."
