The sanctions Key ship insurer the China P&I Club will halt indemnity<br />coverage for tankers carrying Iranian oil from July. This is the first<br />sign that refiners in China, Iran's top crude buyer, may struggle to<br />obtain the shipping and insurance to keep importing from the Middle<br />Eastern country. Iran's other top customers -- India, Japan and South<br />Korea -- are running into similar problems, raising questions on how<br />Tehran will be able to continue to export the bulk of its oil. Iran<br />sells most of its 2.2 million barrels per day of oil exports in Asia,<br />where China, India, Japan and South Korea are the four biggest buyers.
