Chinese stocks rebounded on Friday afternoon from a lacklustre morning, led by financial shares, which analysts expect to benefit from increasing bullishness about mainland markets.

The CSI300 Financials sub-index jumped nearly 3 per cent, with brokerages CITIC Securities, China Merchants Securities and Western Securities all up more than 8 per cent.
