China has, on three occasions, placed a "technical hold" on Azhar's designation as a global terrorist in the 1267 committee.
After the Pulwama suicide car-bombing by the JeM that killed more than 40 Central Reserve Police Force (CRPF) troopers on February 14, France is spearheading a renewed effort with British and the USA backing to put sanctions on Azhar.
On Tuesday, China had said that "responsible and serious discussions" are needed ahead of the United Nations Security Council (UNSC)'s sanctions committee meeting. The no-objection period deadline was scheduled to end at 3 PM local time on Wednesday (12:30 AM IST on Thursday).
Without naming China, India's permanent representative to the UN Syed Akbaruddin in a tweet said, "1 big state holds up, again." and added, "Grateful to the many states - big & small - who in unprecedented numbers, joined as co-sponsors of the effort".
India on Saturday said all UNSC members were aware about the JeM training camps and the presence of terror group's chief Masood Azhar in Pakistan, and urged them to designate him as a global terrorist. "This has prevented action by the worldwide community to designate the leader of (JeM), a proscribed and active terrorist organization which has claimed responsibility for the terrorist attack in Jammu and Kashmir on 14 February 2019", it added.
Beijing had always demonstrated responsibility, and it had been in contact with the parties on the resolution and always taken an appropriate stance, a spokesman for the Chinese foreign ministry said.
India was perturbed about whether China would let the process conclude or place a "technical hold" on it-as it has done several times in the past.More news: John Bolton: Donald Trump optimistic for more North Korea talks

While there was earlier dismay in India that Beijing did not condemn the terrorist attack "in Kashmir" in its statement on the Pulwama attack, New Delhi has taken note of the fact that China had backed the UNSC resolution condemning the terrorist attack in Kashmir.
The blocking of the resolution, jointly presented by the United States, United Kingdom and France, seems to have greatly disappointed New Delhi.
The travel ban entails preventing the entry into or transit by all states through their territories by designated individuals.
"Azhar is the founder and the leader of the JeM, and he meets the criteria for designation by the United Nations", State Department Deputy Spokesperson Robert Palladino told reporters at his daily news conference. However, hours before the deadline expires for any member at UNSC, India has reached out to key players in order to mobilise support.
In the wake of the Pulwama terror attack, India launched a major diplomatic offensive against Pakistan, holding briefing for envoys of 25 countries, including those from the five permanent UNSC members - the US, China, Russia, the United Kingdom and France - to highlight Islamabad's role in using terrorism as an instrument of state policy.
On Monday, India's foreign secretary Vijay Gokhale met USA secretary of state Mike Pompeo to press the terror issue. It would have also bolstered India's assertion that Pakistan is the epicentre of terrorism in the South Asian region.
