Tanzania is holding peace talks on Monday for South Sudanese political parties who have been in a civil war for the past 10 months.
"We are hopeful that something will come out from Arusha," Tanzanian Ministry of Foreign Affairs spokesperson Mawien Makol said.
The last time the rivals met was in August in Ethiopia, where they signed a ceasefire that fell apart a couple of days later. That was the fourth truce agreement between the factions in 8 months.
Millions of people are living under the threat of famine and starvation, and as 19 aid agencies have warned that threat increases as long as this civil war continues.
Thousands of South Sudanese have been killed in the fighting. Nearly two million have been displaced by government military soldiers and militia forces. Dilapidated U.N. peacekeeping bases are housing around 100,000 people.
The fighting broke out on December 15, last year, when President Salva Kiir accused the deposed vice president of attempting to overthrow the South Sudanese government.
