津巴布韦领导人一致抗议国际制裁

Zimbabwe's three leading figures have condemned international sanctions on the country at a World Economic Forum conference in Tanzania.

津巴布韦三位主要领导人出席坦桑尼亚世界经济论坛时，一致谴责国际社会对其实行的制裁。

President Mugabe's presence was not announced in the programme

In a rare show of unity, President Robert Mugabe, Prime Minister Morgan Tsvangirai and his deputy Arthur Mutambara appealed for（恳求，请求） investment.

Only Mr Tsvangirai had been expected to represent Zimbabwe at the forum in Dar es Salaam.

But President Mugabe and Mr Mutambara made a surprise appearance.

Despite the history of conflict, the three men put on a civil front, though Mr Mutambara did not resist a rather barbed（讽刺的） reference to having gone to a previous World Economic Forum from a prison cell, says the BBC's Andrew Walker, who is in Dar es Salaam.

The Zimbabwean leaders were speaking to an audience with a large business contingent（分遣队，偶然事件） .

Several of them welcomed the show of unity and the more stable economic environment that Zimbabwe now has, our correspondent says.

But there were also some concerns expressed about how durable the improvement will be, he adds.

Mr Tsvangirai said his country no longer represented a risk to investors.

"The political crisis does no longer exist.

"The country is making progress and it's time that investors started looking at Zimbabwe from a different perspective," he was quoted by Reuters news agency as saying.

Mr Mugabe reiterated（重申） the call for an end to sanctions.

"Why the sanctions should be imposed on us we don't understand to tell you the truth, and this from Europe and America and not from the rest of the world," he said.

If the three leaders were here to give an invitation to investors, their joint appearance may have helped a little, our correspondent says.
