Chinese shares ended lower on Thursday on concerns about Sino-U.S. trade and slowing growth, but the country's main stock indexes posted their biggest monthly gains in nearly four years on investor hopes for government stimulus and policy support.
At the close, the Shanghai Composite index was down 0.44 percent at 2,940.95. The index ended February with a 13.8 percent rise, its biggest monthly gain since April 2015.
The blue-chip CSI300 index finished down 0.25 percent, but posted its biggest monthly gain since April 2015, rising 14.6 percent.
The smaller Shenzhen index ended up 0.35 percent and the start-up board ChiNext Composite index was higher by 1.004 percent.
Factory activity in China contracted for the third straight month in February, and export orders fell to the lowest level since the global financial crisis, underscoring concerns over a slowdown in the world's second-largest economy.
