The Chinese President Hu Jintao, who's visiting the United States, has acknowledged that China still needs to do a lot more on human rights and said his country was willing to engage in dialogue on the issue. Mr Hu made the unusually candid comments at a joint news conference with President Obama at the White House in response to a question from a reporter.

"China is a developing country with a huge population and also a developing country in a crucial stage of reform. In this context, China still faces many challenges in economic and social development, and a lot still needs to be done in China in terms of human rights."

Mr Hu had earlier failed to answer a question on human rights, blaming technical difficulties. On the dispute over China's currency, President Obama said the yuan was undervalued.

"There needs to be further adjustment in the exchange rate, so we'll continue to look for the value of China's currency to be increasingly driven by the market, which will help ensure that no nation has an undue economic advantage."

Tunisia's interim President Fouad Mebazaa has promised to deliver a fresh start for his country and to protect the will of the people. He made the pledge in his first televised speech. Wyre Davies reports from Tunis.

The interim President Fouad Mebazaa said he guaranteed that the transitional government would ensure a total break with the past. He also said there would be an independent judicial system, freedom of the press and a commission to investigate corruption under the previous government. An amnesty for all political prisoners has already reportedly begun. The interim president also promised to detain those responsible for orchestrating violence against pro-democracy campaigners.

United Nations says it's sending a team of human rights officials to Tunisia to advise the new government and look into the recent violent turmoil. The UN commissioner for human rights, Navi Pillay, said she was responding to the scale of violence before the overthrow of President Ben Ali last Friday.

"It is a matter of great sadness that so many lives had to be lost to bring about this opportunity. My office has received information concerning more than 100 deaths over the last five weeks as a result of live fire."

In Tunisia, the situation remains tense, but curfew hours have been reduced.

The first official results from this month's referendum in southern Sudan indicate that people voted overwhelmingly in favour of independence for the region.

The UN Security Council has unanimously agreed to send 2,000 extra peacekeepers to Ivory Coast. The country has been in deadlock with Laurent Gbagbo refusing to cede power to his rival Alassane Ouattara, who's widely recognised as the winner of the presidential election. Barbara Plett reports from the UN.

UN patrols have been attacked, and their movements severely restricted by forces loyal to the incumbent President Laurent Gbagbo, who accuses the UN of bias because it supports his rival Alassane Ouattara.

They'll also comprise a rapid reaction force to respond to emergencies and strengthen attempts to protect civilians and investigate reported atrocities.
