India has been asserting that it produced "solid evidence" for securing a ban on the Pathankot attack mastermind, adding that the actions of the Pakistan-based terrorist are well documented.
"We have talked about our position many times. We believe that the principles of objectivity and professionalism and justice shall be upheld," Mr Geng told media briefing in Beijing.
Mr Geng was responding to a question whether there can be a forward movement over China's repeated technical holds to block India's move to get a UN ban on Azhar.
"At present, some members have disagreement over the listing matter. And China stands ready to remain in coordination and communication with the relevant parties on this issue," he said.
Beijing put a technical hold to a move in the UN by the US and other countries to declare Azhar a terrorist for his role in the Pathankot terror attack.
Last year China had put technical holds on India's application to designate Azhar as a terrorist.
Foreign Secretary S Jaishankar, who held strategic dialogue with Chinese officials in February here, said, "in the case of Azhar, Jaish itself is proscribed under 1267. So the proof is in 1267 committee action. In this case what he has done, extent of his actions are well documented."
"It is not that the burden of proof is on India to convince. The sponsors (US and other countries) seem to be very well convinced otherwise they would not have taken the initiative to move the proposal," he had said, referring to the US, the UK and France pressing for action on Azhar.
The 1267 Committee is consist of members of the UN Security Council.
Mr Geng's response to the Azhar issue followed a two-day meeting of the BRICS Foreign Ministers who took a strong stand on countering terrorism and working out international mechanisms to curb terrorism.
Minister of State for External Affairs V K Singh, who took part in the meeting, said BRICS should back a comprehensive convention on terrorism in the UN shedding ambiguity about good and bad terrorists.
"We have a consensus among the BRICS countries that all (kinds of) terrorism must be condemned and various measures must be taken to cooperate so that terrorism does not spread and harm any one of our countries," Mr Singh had told a joint press conference with BRICS Foreign Ministers here yesterday.
Mr Geng said today that BRICS countries had a working group on counter terrorism. China shares common position on the need for a comprehensive convention on international terrorism. "As for convention on counter terrorism, I believe China and other BRICS counties have a similar position...We hope UN General Assembly can pass a compressive convention on terrorism...," he added.
