TOKYO, Feb 1 (Reuters) - U.S. President Donald Trump's arguments on border tax aimed at limiting imports into the United States were contradictory to his criticism of a weak yen, and such one-sided arguments were destructive, an adviser to Prime Minister Shinzo Abe said.
Economic theory suggested implementing a U.S. border tax would cause the dollar to appreciate, Koichi Hamada, emeritus professor of economics at Yale University and cabinet adviser, said at a seminar on Wednesday.
Pushing for border tax and criticizing a weak yen at the same time were contradictory, Hamada said, adding that forcing such an argument was destructive to Japan and world economy.
