LONDON (Reuters) -Oil prices steadied on Wednesday, with benchmark Brent holding above $77 a barrel, after steady sell-offs driven by expectations of reduced Chinese demand and diminishing concerns the conflict in the Middle East could spread and disrupt supply. Brent crude futures were up 14 at $77.34 a barrel by 1142 GMT. As expectations swirl economic weakness in China, the world's biggest crude importer, will subdue demand, stocks in the United States, the world's biggest producer and consumer of oil, are set to rise.
