Pyongyang is trying to affect the ROK election with the launch, hoping it will lead to leaders in Seoul taking softer stance on the DPRK, Wang Fan,a professor at China Foreign Affairs University said.
"But the launch is a double-edge sword that will also result in a new round of sanctions from the international community against the DPRK."
He added that a successful rocket launch would also raise Pyongyang's bargaining power with the US and the ROK.
