Chinese shares closed almost flat Friday with low trading volume, ending a week of stable gains with mixed performance.

The benchmark Shanghai Composite Index went up 0.01 percent at 3,268.72 points while the Shenzhen Component Index closed 0.37 percent lower at 10,614.08 points.

Trading remained subdued with combined turnover at the two bourses reaching 479.9 billion yuan (71.9 billion U.S. dollars).

During the week, the Shanghai Composite Index climbed 1.88 percent, the biggest weekly gain in more than four months.

Shares in the oil industry and recently listed stocks were among the biggest winners Friday, with Sinopec Shandong Taishan Petroleum jumping by the daily limit of 10 percent.

Shares related to Xiongan New Area, a new economic zone about 100 kilometers southwest of Beijing, staged relatively strong performance after the country's top economic planner said it is now actively planning the zone. China Fortune Land Development reportedly signed development agreements in the area and saw its shares up 4.25 percent.

A spokesperson for the National Development and Reform Commission said Friday that it will push for the planning of Xiongan as a new home for Beijing's "non-capital" functions, and drive coordinated development of the Beijing, Tianjin and Hebei region.

The ChiNext Index, which tracks China's NASDAQ-style enterprises, lost 0.63 percent to close at 1,821.8.
