The agreement came as Chinese President Xi Jinping met his Russian counterpart Vladimir Putin on Sunday night in Xiamen, Fujian province, ahead of Monday's Brazil, Russia, India, China and South Africa (BRICS) summit.
Meanwhile, the Chinese Foreign Ministry issued a statement, expressing firm opposition to and strong condemnation of the nuclear test.
Both leaders have agreed to stick to the goal of de-nuclearisation on the Korean Peninsula and keep close communication and coordination to deal with the new situation.
The statement further read that the move goes against the objective of the de-nuclearisation of the Korean peninsula, which has been endorsed by the country itself.
"India also remains concerned about the proliferation of nuclear and missile technologies which has adversely impacted India's national security," it added.
