The UN Security Council has agreed to extend the mandate of its security mission in East Timor by one year.
The in principle renewal came after East Timor appealed to the UN to maintain a strong presence in the troubled South-East Asian nation after recent attacks on its top two leaders.
A formal vote on the extension will be held on Monday.
In the wake of an assassination attempt on the country's president earlier this month, he said the security environment remained "fragile and volatile", adding that the country will need UN support until the next elections, due to be held in 2012.
"We'd hope that it [the extension] will not just be one year but it will be renewed for another … three or four years."

But he warned that the country would remain unstable until political differences and challenges left over from the fledgling country's fight for independence are resolved.

"The IDP situation is a political and security concern as well as a humanitarian one, and largely considered as neither short-term, nor easily fixed," he said.
The country also faces challenges from former soldiers and fighters loyal to Reinado, he said.
"The fact that Timor Leste came so close to a real breakdown shows how important and urgent it is to address a number of issues - the remaining Reinado supporters who are under arrest warrants, the petitioners, the IDPs.
"These pressing issues have been unresolved since the crisis of 2006."
