Zimbabwean President Robert Mugabe, seemingly unfazed by African Union and international pressure to compromise with the opposition on power-sharing, said today that he would only negotiate withthe Movement for Democratic Change if it acknowledges that he is the dulyelected head of state - something the opposition has already said it will notdo.

Speakingat Harare International airport upon his return from the African Union summitin Egypt earlier this week, Mr. Mugabe commended South African President Thabo Mbeki for his efforts to mediate between ZANU-PF and the MDC. The opposition party however has been highly critical of Mr. Mbeki, accusing him of a pro-Mugabe bias in thatmediation.

Oppositionleader Morgan Tsvangirai has said he will only enter talks on power-sharing on the basis of the results of the first-round elections held on March 29 - and then only if the political violence which has seared the country since the March ballot stops.

But Mr. Mugabe said the opposition must recognize as valid his re-election on June 27 if anydialogue is to take place.

Responding to Mr. Mugabe's statement, MDC spokesman Nelson Chamisa vowed that his party would never recognize Mugabe's re-election.

Meanwhile, South African Deputy Foreign Affairs Minister Aziz Pahad bluntly told Zimbabwe on Friday that it must put a stop to politically motivated violence, warning that if the beating and killing continues Pretoria will haveno choice but to take unspecified unilateral action.

Correspondent Benedict Nhlapho of VOA's Studio 7 for Zimbabwe reported.

Botswana and Tanzaniahave said they do not recognize Mr. Mugabe as the head of the Zimbabwean state.

German Chancellor Angela Merkel condemned his re-election as illegitimate and vowedthat the European Union would seek "all possible sanctions" against hisgovernment.

But Information Minister Sikhanyiso Ndlovu told reporter Blessing Zulu of VOA's Studio 7 for Zimbabwe that Mr. Mugabe must be acknowledged as president of Zimbabwe, insisting that the presidential run-off election held on June 27 was no sham.

Independentanalyst Chris Maroleng said dialogue between the two parties can onlytake place if they waive their preconditions.
