The Japanese yen decelerated early Monday in Asia as investors eye Ukraine news before a busy data week and markets in the United States and Canada were shut for the Labor Day.

Against the US dollar, the yen traded at ¥104.13, up from Friday’s ¥103.70.

On Saturday, European Union leaders agreed to come up with new sanctions against Russia unless the country would scale back its intervention in Ukraine. Some 1,000 troops entered Ukraine.

"I can assure you that everyone is fully aware that we have to act quickly given the escalation on the ground,” said European Council President Herman Van Rompuy at the end of European leaders’ summit.
