TOKYO (AFX-ASIA) - Finance Ministry senior deputy director-general Zenbei Mizoguchi said a stronger yen against the dollar is undesirable and the ministry will take appropriate action if needed. "I believe the current economic fundamentals do not justify a stronger yen against both the euro and the dollar," Mizoguchi told AFX-ASIA at the ministry. "There is currently speculative action centring on the euro so this move will be corrected at some point," he added. "The yen's rise is not desirable and we are ready to take proper action, watching closely market moves."
