SHANGHAI, March 26 (Reuters) - Chinese stocks ended higher on Thursday after volatile trade as a sharp drop in internet stocks was offset by a surge in energy shares triggered by a rebound in oil prices.

But energy shares jumped 3 percent, led by oil companies such as PetroChina and Offshore Oil Engineering as oil prices shot up nearly 6 percent after Saudi Arabia and Gulf Arab allies started air strikes against rebels in Yemen.
Shares in state-backed shipbuilders China CSSC Holdings and China Shipbuilding Industry Company (CSIC) surged by their 10 percent trading limit to hit record highs after executive swaps at the firms' parent companies raised expectations of a merger.
