June 1992, during the long protest at Uhuru Park, both Maathai and President arap Moi travelled to Rio de Janeiro for the UN Conference on Environment and Development (Earth Summit). The Kenyan government accused Maathai of inciting women and encouraging them to strip at Freedom Corner, urging that she not be allowed to speak at the summit. Despite this, Maathai was chosen to be a chief spokesperson at the summit.<ref>Unbowed'. she was a good person ', pp. 226–228.</ref> Push for democracy During the first multi-party election of Kenya, in 1992, Maathai strove to unite the opposition and for fair elections in Kenya. The Forum for the Restoration of Democracy (FORD) had fractured into FORD-Kenya (led by Oginga Odinga) and FORD-Asili (led by Kenneth Matiba); former vice president Mwai Kibaki had left the ruling Kenya African National Union (KANU) party, and formed the Democratic Party. Maathai and many others believed such a fractured opposition would lead to KANU's retaining control of the country, so they formed the Middle Ground Group in an effort to unite the opposition. Maathai was chosen to serve as its chairperson. Also during the election, Maathai and like-minded opposition members formed the Movement for Free and Fair Elections. Despite their efforts, the opposition did not unite, and the ruling KANU party used intimidation and state-held media to win the election, retaining control of parliament. The following year, ethnic clashes occurred throughout Kenya. Maathai believed they were incited by the government, who had warned of stark consequences to multi-party democracy. Maathai travelled with friends and the press to areas of violence in order to encourage them to cease fighting. With the Green Belt Movement she planted "trees of peace", but before long her actions were opposed by the government. The conflict areas were labeled as "no go zones", and in February 1993 the president claimed that Maathai had masterminded a distribution of leaflets inciting Kikuyus to attack Kalenjins. After her friend and supporter Dr. Makanga was kidnapped, Maathai chose to go into hiding. While in hiding, Maathai was invited to a meeting in Tokyo of the Green Cross International, an environmental organisation recently founded by former Soviet leader Mikhail Gorbachev. When Maathai responded that she could not attend as she did not believe the government would allow her to leave the country and she was in hiding, Gorbachev pressured the government of Kenya to allow her to travel
