Movement for Democratic Change (MDC) Leader Morgan Tsvangirai (C) leaves the Rainbow towers in Harare on October 16. Zimbabwe President Robert Mugabe and rival Tsvangirai are set to resume power-sharing talks for a fourth day to end a spat on key cabinet posts holding up a new unity government.

Jendayi Frazer, the top US diplomat for Africa, says The United States will consider new sanctions against Zimbabwean President Robert Mugabe’s government if a power-sharing deal collapses.

Frazer says she was not optimistic after talks remained deadlocked between Mugabe and his main rival Morgan Tsvangirai.

Frazer told a group of reporters in Tokyo "If it doesn’t work then we are going to continue the pressure that we’ve put on the government. We will look at new sanctions against President Mugabe and his regime".
