NEW DELHI, Dec 23 (Reuters) - India's State Trading Corp STCI.NS has received the highest bid at $288.3 per tonne for its wheat export tender offering 200,000 tonnes, trade sources said on Monday, more than the government's floor price of $260 a tonne. There were 10 bidders for the global tender, said one of the sources. The state-run trader issued the tender last month offering the grain from government warehouses for shipment between Jan. 4 and Feb. 3 on the country's west coast.

The tender is part of the Indian government's plan to sell 2 million tonnes of the grain overseas until March, as it attempts to trim bulging stocks. Earlier, state-run MMTC Ltd MMTC.NS received the highest bid at $283.11 a tonne for its wheat export tender from the east coast.
