The Bank of Japan has announced new measures to boost the economy after holding an emergency meeting. The bank said it will inject 114 billion dollars into the economy through buying up bonds and other assets. The Bank of Japan said the move will firmly support country's economic developments toward recovery.The government has welcomed the bank's decision. It has been concerned about the recent return of deflation. However, analysts said the operation looked more like a political gesture than a real move to support the economy. The economy also faces the challenge of a rise in the value of the yen, which makes the country's exports more expensive in global markets.
