MOSCOW (Reuters) - The Russian rouble firmed to a more than three-week high against the dollar on Monday, buoyed by rising oil prices but restrained by fears about a possible Russian invasion of Ukraine, plans for which Moscow has repeatedly denied.
At 0730 GMT, the rouble gained 0.3% to 75.60 against the dollar after touching its strongest level since Jan. 13 of 75.5825.
