Japan economy minister Amari: Difficult for countries to conduct FX intervention

Reuters with comments from Japan economy minister Amari, speaking in parliament:

• Can't conclude current moves are excessive yen weakness
• In general, it has become difficult for countries to conduct fx intervention, take steps to directly weaken their currencies
• Hope forex rates stabilise at levels reflecting fundamentals

• Japan's economy cannot survive yen rises to around 80 vs dollar, though ideally it should be strong enough to weather yen rises
