MOSCOW, Aug 27 (Reuters) - The rouble made slight gains

against the dollar on Wednesday ahead of month-end tax payments

that support the Russian currency.

At 1030 GMT, the rouble was up 0.12% at 80.4 against

the dollar, according to data compiled by LSEG based on

over-the-counter quotes. The rouble closed Tuesday's session at

80.49, notching up 0.25% over the day's trade.

The rouble was 0.17% stronger at 11.21 against China's yuan,

the most traded foreign currency in Russia.

The Russian currency has received support this week ahead of

a single tax payment Russian corporations will make on August

28, in which exporters usually sell their foreign currency

earnings to meet local liabilities.

Brent crude oil, a global benchmark for Russia's

main export, was down 0.15% at $67.12 per barrel as investors

watched for fresh developments in the Ukraine conflict and

digested the introduction of U.S. tariffs on India.
