SHANGHAI, Dec 21 (Reuters) - China stocks rebounded on Wednesday, as fears of a liquidity squeeze in the banking system subsided after risks from a bond scandal appeared contained, and on a pledge to deepen reforms in state-owned sectors.
The blue-chip CSI300 index rose 0.9 percent, to 3,338.54 points, while the Shanghai Composite Index gained 1.1 percent to 3,137.43 points, both snapping a two-session losing streak.
Investors relaxed after Sealand Securities, a brokerage embroiled in a scandal, said on Wednesday it would take responsibility for forged bond agreements.
Sealand's commitment eased concerns of a liquidity squeeze, triggering a sharp rebound in bond prices.
The State-owned Assets Supervision and Administration Commission said China would vigorously push forward mixed-ownership reforms in sectors including telecommunications, aviation and defence.
Most sectors gained, led by infrastructure and transport plays, while properties and banks steadied.
