Flights to Wuhan will be suspended outright, while the number of flights to Beijing and Shanghai will be reduced from Friday due to a drop in demand, the broadcaster reported.
Earlier on Wednesday, a number of major airlines announced the suspension of flights to China.
Among them, British Airways, Iberia and Lufthansa Group, comprising Austrian Airlines, Lufthansa and Swiss, announced that all their services to China would be grounded.
In the case of Lufthansa Group, all flights to and from China will be suspended until 9 February.
On Wednesday, Finland confirmed its first case of the novel strain of viral pneumonia. The infected person is a 32-year-old woman who left Wuhan five days ago.
The novel strain of coronavirus was first detected in the central Chinese city of Wuhan in December. It has since spread within China and to at least 18 other countries.
So far, there are about 6,000 confirmed cases in China alone. 133 people in China have died after contracting the virus.
