* China stocks subdued, yuan steady

* China 2023 GDP growth forecast cut to 5.0% - poll

* CEE currencies tumble, Polish zloty erases YTD gains

* Czech central bank's Prochazka says no rate cut this month

Sept 12 (Reuters) - Emerging market currencies were muted on Tuesday as the dollar bounced back a day before key data on U.S. consumer prices, while Chinese equities lost steam after gains in the previous session on signs of stabilisation in the world's second largest economy.

MSCI's index for EM currencies held near the unchanged mark at 0912 GMT, while stocks edged 0.2% lower.

EM assets had received a boost on Monday after strong lending data and more stimulus measures from China bolstered risk sentiment, with the Chinese yuan bouncing off a 16-year low against the dollar.

On Tuesday, China's blue-chip index fell 0.2%, while the yuan held steady with a warning from China's central bank against overshooting of the currency supporting traders' expectations for more stability in the near term.

China's economy will grow less than previously thought this year and next due to a struggling property market, according to a Reuters poll of economists, who predicted the economy would grow 5.0% this year, lower than 5.5% forecast in a July survey.

U.S. August consumer prices data for August due on Wednesday will help shape the outlook for U.S. interest rates and the dollar. The data is expected to show core inflation eased to 4.3% year-on-year.

"With a stronger than expected (U.S.) inflation print, it could convince people that the Fed has still has work to do," said Jonathan Petersen, senior markets economist at Capital Economics.

"It could push U.S. rates higher relative to elsewhere, which would be positive for the dollar and negative for CEE and another emerging market currencies."

The Russian rouble hit its strongest level in almost six weeks against the dollar before paring some gains as President Vladimir Putin promised no sudden moves to limit rouble volatility.

Elsewhere, central and eastern European currencies also took a tumble, pressured by rising bets of monetary policy easing given cooling inflation in the region.

The Czech crown slipped 0.3% against the euro to hit its lowest in 11 months. Board member Jan Prochazka was quoted as saying the central bank can start to discuss a possible lowering of interest rates at its policy meeting in September although a cut then cannot be expected.

The Polish zloty was down 0.8% against the euro, hitting its lowest level since April and nearly erasing all of its 2023 gains.
