China's largest oil and gas company, PetroChina Ltd., has announced that its profit for the first six months of 2010 increased by 29 percent as compared to 2009.

The company said that it posted profit on account of higher oil prices that helped to offset weaker margins in its refining biz.

In addition, the Beijing-based company said that the revenue in the first six months of this year was 65.3 billion yuan ($9.6 billion), up from of 50.5 billion yuan compared to 2009.

China Nuokang Bio-Pharmaceutical Inc., which focuses in blood and cardiovascular treatments, has announced that the company’s profit in the three month period ended June 2010 increased by 10 percent.

The company attributed the overall growth to the sales from its major product.

In a statement, the company stated that sales of China Nuokang's bleeding control product, Baquting, grew by 8.2 percent to 77.8 million yuan ($11.5 million).
