Reuters on Jan. 11 reported that China plans to set a lower GDP growth target of 6-6.5 percent in 2019 compared with last year's target of "around" 6.5 percent.

The official target will be unveiled at the annual parliamentary session in March.

On Monday, China will report economic growth data for 2018's last quarter. Growth is expected to have slowed to 6.4 percent, the weakest pace since the global financial crisis, a Reuters poll showed.
