MOSCOW, Feb 19 (Reuters) - The Russian rouble was little

changed against the U.S. dollar on Wednesday as investors

awaited further developments on talks between Moscow and

Washington on ending the war in Ukraine.

At 0830 GMT, the rouble was up 0.3% at 91.25 against the

dollar on the Moscow Exchange, close to a five-month high

reached last week. But some analysts urged caution and said

excessive optimism was premature.

"The events are bringing an excessively optimistic mood and

volatility to the market," BSC brokerage analysts said. "It too

early to talk about real changes."

The rouble was also up 0.2% against China's yuan, the most

traded foreign currency in Russia.

The Russian currency has gained about 20% against the dollar

this year, mostly on expectations of easing geopolitical

tensions between Russia and the West.
