Japan announced its current account surplus hit a 9-year high in 2016, helped by lower costs for imported oil and improved exports, AP reported. The perennial trade surpluses Japan runs with the U.S. are a sore point for U.S. President Donald Trump, and the data announced Wednesday came just as Prime Minister Shinzo Abe was preparing for summit meetings with Trump later in the week. They also followed the release of U.S. data showing Japan logged the second largest trade surplus with the U.S. last year, after China, at $68.9 billion dollars. China's, at $347 billion, was the highest. The current account is a wide gauge of trade and includes investment flows as well as exports and imports. The 20.65 trillion yen ($183.7 billion) worldwide surplus was up 25 percent from a year before and the second highest on record. Exports fell by less than imports, leaving a goods trade surplus of 5.58 trillion yen ($49 billion), after a deficit of 628.8 billion yen in 2015.
