Checking the usual rumor sources shows that this should happen around noon local time, which has just passed. Expect some news within the next hour or two.

China launches high-resolution remote sensing satellitesTAIYUAN, Dec. 28 (Xinhua) -- China launched a pair of 0.5-meter high-resolution remote sensing satellites from the Taiyuan Satellite Launch Center in Shanxi Province on Wednesday.
The satellites, SuperView-1 01/02, blasted off at 11:23 a.m. Beijing time on the back of a Long March 2D rocket, according to the center.
They are able to provide commercial images at 0.5-meter resolution.

There are some rumors out there (starting with a tweet from a CCTV correspondent) that something went wrong after going into orbit - either the orbit is off or the main sats might be experiencing problems maybe?
BY70 did contact with Earth as planned.

Two more objects found in a similar orbit. Hmm......

An obvious deduction is that the orbit circularisation manoeuvre failed to take place.

Let's see if the second TLE set confirms this.

I wonder if CZ-2D second stage makes two burns. I'd think of insufficient velocity at insertion.

I seem to remember from descriptions many years ago that the second stage verniers were used for orbit circularisation.

To be precise:

2016-083C/41909 in 212 x 524 km x 97.59°

Well, this is not a separate burn, just a continuation of the 2nd stage main engine burn. See this from CZ-2D/JL-1 launch in 2015:

China Launches High-resolution Remote Sensing Satellites

Published on Dec 27, 2016
China launched a pair of 0.5-meter high-resolution remote sensing satellites from the Taiyuan Satellite Launch Center in Shanxi Province on Wednesday.
The satellites, SuperView-1 01/02, blasted off at 11:23 on Wednesday. Beijing time on the back of a Long March 2D rocket, according to the center.
They are able to provide commercial images at 0.5-meter resolution.
A small satellite built by high school students in Beijing was also launched into space in Wednesday's mission.
More than 40 students from the Beijing Bayi High School built the satellite under the instructions from experts. The satellite will stay in space for more than 180 days.
