He distributed over 200 computers to Manicaland schools and said that food and farm equipment would also be sent. On the same day, Mugabe said at a rally in Mahusekwa that some businesses were raising prices with the intent of causing the people to suffer, hoping that they would blame the government for their suffering and vote for the opposition as a result. The European Union expressed concern on 10 March that "the humanitarian, political and economic situation in Zimbabwe and conditions on the ground" might "endanger the holding of free and fair parliamentary and presidential elections". It said that European observers had not been invited. While not inviting any observers from the EU or the United States, Zimbabwe has invited 47 observer teams, including observers from the Southern African Development Community (SADC), the African Union, China, Russia, and Iran. On 11 March, the arrival of the first 50 observers from SADC was reported, with more expected. SADC Secretary-General Tomaz Salomao said in a press conference in Harare on 12 March that SADC was confident "that the tradition of peace encapsulated in the unquestionable political maturity and tolerance shall, once again guide Zimbabweans as they go to the polls". In light of Zimbabwe's dramatic inflation rate, Mugabe massively raised the salaries of members of the security forces in February, and on 10 March he approved raises for teachers and civil servants. At around the same time, he signed the Indigenisation and Economic Empowerment Bill, which requires all businesses to be majority owned (at least 51%) by black Zimbabweans. Mugabe subsequently accused business of raising prices to nullify the benefit of the pay raises, demanding that the price increases be reversed and warning that "profiteering" white-owned businesses would be taken over by the government. Human Rights Watch stated that the Electoral Commission was inadequately prepared for the polls and that the opposition was not being treated equally to the governing ZANU-PF by the authorities. The government rejected these accusations; Deputy Information Minister Bright Matonga said that both ZANU-PF and the MDC were represented on the Electoral Commission and that Human Rights Watch's report reflected an agenda. In a report issued on 19 March, Human Rights Forum claimed strong media bias in favour of Mugabe and the use of intimidation and threats against opposition supporters; it also alleged that the Electoral Commission is merely a front for the Registrar's Office, which it said is partisan in favour of ZANU-PF. Mugabe has used the campaign slogan "vote for the fist", reflecting ZANU-PF militancy; the MDC replied to this slogan by saying that "we cannot feed people with clenched fists", while Makoni has said that "the fist has become a hammer smashing the country".
