Last week, China for the fourth time blocked a bid at the UN by the US, France, and Britain to list Azhar as a global terrorist, citing a lack of consensus among the members of the Al-Qaeda Sanctions Committee of the UN Security Council.
"I think it's an unfortunate move on China's part and I question the logic of continuing to block sanctions on known Pakistan-based terrorists at the United Nations," Jeff Smith, a research fellow at the Heritage Foundation told PTI.
Smith said that China was "clearly" seeing its action as a favour to its all-weather friend, Pakistan. "But the policy is increasingly undermining China's own strategic interests and stated foreign policy objectives," he said, noting that in September, China had, for the first time, relented to including specific criticism of the Jaish-e- Mohammed (JeM) and other Pakistani terror outfits in the statement issued at the BRICS summit in Xiamen.
During their summit in China this year, Brazil, Russia, India, China and South Africa named Pakistan-based terror groups like the LeT and the JeM were for causing violence in the region. They also asserted that those responsible for committing, organising or supporting terror acts must be held accountable.
"It grievously undermines an increasingly prominent Chinese narrative about the need to take a tougher line on terrorism broadly, and in Afghanistan specifically," Smith said.
"Its actions are also doing material harm to the health of a China-India relationship already under duress," he said.
The Permanent Mission of the United States to the United Nations said that the Committee discussions over whether to add an individual or entity to the 1267 sanctions list are confidential to the committee.
"However, we would support efforts to list Azhar, Jaish-e Mohammed's founder and leader, on the 1267 Sanctions List and would encourage others to support his listing as well," a spokesperson for the US mission in New York said.
According to Rick Rossow from Center for Strategic and International Studies (CSIS), an American think-tank, China's latest move affirmed Delhi's belief in Sino-Pakistani collusion.
Rossow alleged that China continued to use the international system where it saw fit, "such as this vote", while undermining the international system in other areas, "such as maritime law".
"The timing is significant, coming on the heels of Washington's stronger rhetoric against Pakistan's support for terrorism. Much like the announcement of the China-Pakistan Economic Corridor, this decision was another Chinese lifeline to Islamabad at a precarious time," Rossow said.
Aparna Pande, Director of Initiative on the Future of India and South Asia at Hudson Institute think tank, said she was not surprised by Beijing's decision. "While China worries about Islamist radicals it is concerned primarily with Uyghurs and on that front it will apply pressure on Pakistan," she noted.
"When it comes to jihadists who target India, China does not see it as in its interest to force Pakistan. Further, being seen as Pakistan's benefactor in the international arena is another benefit for Beijing," Pande said.
The JeM, founded by Azhar, has already been in the UN's list of banned terror outfits. Last March, China was the only member in the 15-nation UN Security Council to put a hold on India's application.
The other 14 members supported New Delhi's bid to place Azhar on the sanctions list that would subject him to an assets freeze and travel ban. Azhar is accused of several terrorist attacks in India, including one on the Pathankot air force station in January 2016.
