The United States has proposed that United Nations Security Council blacklist South Sudan opposition figure Riek Machar.
U.S. also wants blacklist of South Sudan army chief Paul Malong and South Sudan Information Minister Michael Makuei.
The United States circulated the three names to the 15-member council in an annex, seen by Reuters, to a draft resolution that would place an arms embargo on the world’s newest nation amid warnings by a senior U.N. official of possible genocide.
If the blacklist is designated by the council, the men would be subjected to a global asset freeze and travel ban.
The annex to the draft resolution on Friday accused Malong of being responsible for efforts to kill Machar and said that the army chief had expanded or extended the conflict in the country by breaching a cessation of hostilities agreement.
However, Veto-carrying members, Russia and China both opposed the arms embargo and further targeted sanctions.
Deputy Russian U.N. Ambassador Petr Iliichev said on Thursday that sanctions against South Sudanese leaders would “be the height of irresponsibility now.”
Political rivalry between South Sudan’s President Salva Kiir, an ethnic Dinka, and his former deputy Machar, a Nuer, led to civil war in 2013 that has often followed ethnic lines.
The pair signed a shaky peace deal last year, but fighting has continued and Machar fled the country in July.
Machar was in Democratic Republic of Congo, then Sudan and was most recently in South Africa for medical treatment.
The annex to the draft text accused Machar of entering “into alliances with Equatorian rebel groups to work to overthrow the South Sudanese Government” and said “forces allied with Machar have raided villages and abducted civilians and aid workers.”
The Security Council set up a targeted sanctions regime for South Sudan in March 2015 and has so far blacklisted six generals – three from each side of the conflict – by subjecting them to an asset freeze and travel ban.
In September 2015 the United States proposed that the Security Council sanction Malong, but Russia, Angola and Venezuela objected.
