UNITED NATIONS: China has blocked a request from India to add the head of the Pakistani militant group Jaish-e-Mohammad (JeM) to a UN sanctions blacklist, UN diplomats said, eliciting an angry reaction from the Indian government.

India accused Masood Azhar of masterminding a fatal attack on the Pathankot air base in India in January.

India had requested that its leader be added to a UN Security Council blacklist of groups linked to Al-Qaeda or Daesh, the diplomats said, but China objected.

Chinese Ambassador Liu Jieyi said that the request to add the militant leader to the UN Al-Qaeda/Daesh sanctions list did not meet certain requirements, but did not elaborate.

“Any listing would have to meet the necessary requirements,” said Liu. “It is the responsibility of all members of the council to make sure that these requirements are followed.”

The Kashmir-based group JeM has already been blacklisted by the 15-nation Security Council, but not its leader, Maulana Azhar, a hard-liner and long-time foe of India.

“We find it incomprehensible that while the Pakistan-based Jaish-e-Mohammad was listed ... as far back as 2001 for its well-known terror activities and links to Al-Qaeda, the designation of the group’s main leader, financier and motivator, has been put on a technical hold,” Indian government spokesman Vikas Swarup said in Washington.

“This does not reflect well on the determination that the international community needs to display to decisively defeat the menace of terrorism,” he told reporters on the sidelines of a nuclear summit in the US capital.

It was not immediately clear why China requested that a hold be placed on the Indian request to blacklist Masood Azhar. Technical holds can be lifted and often arise when a Security Council member wants more information. But sometimes they lead to a permanent blocking of a proposed blacklisting.

Asked about China’s decision to place a technical hold on the proposed blacklisting of Masood Azhar, Chinese UN Ambassador Liu Jieyi offered no details.

“Any listing would have to meet the requirements” for blacklisting, he said.

Pakistani security officials have said that a special investigation team set up in Pakistan to probe the Pathankot attack found no evidence implicating Masood Azhar.

If Masood Azhar was blacklisted by the UN Security Council, he would face a global travel ban and asset freeze.

The Jan. 2 attack at Pathankot was followed by a raid on an Indian consulate in Afghanistan that has also been linked to Jaish-e-Mohammad.

JeM militants are blamed for a 2001 attack on India’s parliament that nearly led to a war between the nuclear-armed rivals.
