The measures would form part of plans to renew a UN political mission to Haiti which expires on Friday night. It comes as the impoverished country slides into chaos, with deadly gang violence soaring, fuel shortages and food prices climbing.

The individual sanctions would include travel bans and asset freezes, according to a draft text seen by AFP.

China has taken an increasingly prominent role in the issue of Haiti at the UN in recent years, largely because Port-au-Prince has recognized Taiwan -- the self-ruled, democratic island that Beijing views as its own territory and has vowed to seize one day, by force if needed.

Countries that have diplomatic relations with China usually refrain from having official exchanges with Taiwan.

At the UN, Beijing has taken a harder line on Haiti, though it denies any link between its stance and the Taiwan issue.

A Chinese diplomatic source told AFP that it was necessary to push political authorities in Haiti to act, and to put those responsible for the violence on notice with legal sanctions.

At least 89 people have been killed in Port-au-Prince alone this week after days of gang violence, and aid agencies have said the region is dangerous to access.

The crushing poverty and widespread violence is causing many Haitians to flee to the Dominican Republic, with which Haiti shares a border, or to the United States.

The Security Council is debating whether to extend the special UN political mission to Haiti, known by its acronym BINUH, to 2023.

A vote had initially been scheduled for Wednesday, but with Council members negotiating the request it could be pushed back to Friday.
