SINGAPORE, March 27 (Reuters) - Chicago corn futures inched lower on Monday, retreating from a more than three-week high hit in the previous session as traders assessed uncertainties about the Black Sea grains deal, although strong Chinese demand lent some support to the market.

Soybean and wheat futures also ticked down.
