The UN Security Council unanimously adopted a resolution on Tuesday establishing a sanctions regime for South Sudan in a bid to pressure warring sides to put an end to 13 months of conflict.
The US-drafted resolution threatens to blacklist members from either side of the conflict who attempt to undermine security or interfere with the ongoing peace process. It envisions a peace agreement by Thursday, with a transitional period towards a new government starting April 1.
The resolution also sets up the possibility of creating an arms embargo in the future, but it stopped short of imposing worldwide travel bans and asset freezes on officials involved in the conflict.
Thousands of people have been killed and more than 2 million have been displaced since the war erupted between forces of President Salva Kiir and the rebels loyal to his former vice president, Riek Machar.
The UN peacekeeping forces have been providing security for more than 100,000 civilians, who taken refuge in its bases across the country under threat of death.
