TOKYO -- The dollar edged upward on Tuesday in sluggish Asian trading ahead of "Super Tuesday" voting in US, two European interest rate decisions and a weekend meeting of G7 finance chiefs, dealers said.

The dollar rose to 106.73 yen in Tokyo morning trade from 106.64 in New York late Monday.

The euro declined to $1.4811 from $1.4831, and to 158.10 yen after 158.25.

"Players are refraining from taking positions right now as several key events are coming up, including 'Super Tuesday'," said Saburo Matsumoto, chief forex strategist at Sumitomo Trust Bank.

Twenty-four US states are voting Tuesday in a showdown that amounts to a national primary.

Dealers were also awaiting US economic indicators, including the Institute for Supply Management's non-manufacturing activity index due later in the day.

A meeting of Group of Seven finance ministers and central bank chiefs in Tokyo this weekend is also drawing attention, even if analysts doubt the G7 powers will take any coordinated action to try to boost the global economy.

"If Japan can take the lead in the meeting, it will have a positive impact on Japanese shares and eventually the yen," Matsumoto said.

Finance Minister Fukushiro Nukaga told reporters that they would "discuss the confusion on international financial markets and high oil prices."

"We will send a message that it is important to form relations of trust by clarifying information on the losses of financial institutions," he added.

Traders were also looking ahead to Thursday's interest rate decision by the European Central Bank (ECB).

While stubborn eurozone inflation is expect to spur the ECB to leave rates unchanged for now, analysts nonetheless believe the bank will cut the cost of borrowing later in the year as growth risks increase.

The Bank of England is meanwhile expected to cut its benchmark rate by a further quarter point on Thursday to 5.25 percent, which would be the second cut since December.
