Promises to revise a controversial land law in Peru have halted widespread protests just days before a vote by congress that might see the legislation repealed.
Alan Garcia, the Peruvian president, passed the law by presidential decree earlier this year as part of free trade negotiations with the US.
It allows for the sale of tribal lands, prompting thousands of indigenous farmers to protest saying they fear the loss of land to foreign companies.
Ahead of Friday's vote, Garcia attempted to garner support for the law, arguing in a televised speech that repealing it would be a "historic mistake".
Sixty-five tribes have mobilised against the law, which they say will speed the loss of their land and force them to migrate.
Late on Wednesday they temporarily ended their 10-day protest after a pledge from the congress president that he would revise the law.
The law allows an indigenous community to approve the sale of tribal lands by simple majority vote - eliminating a provision that had made it nearly impossible to develop communal property.
Garcia said on Wednesday that a repeal would condemn Peru's Indian and rural communities to "another century of backwardness and misery".
Protesters are threatening to stop the flow of natural gas and oil through two pipelines in the Amazon jungle. Their action threatens energy supplies.
Thousands had clashed on Wednesday with police in the jungle city of Bagua and nine civilians were treated for injuries.
Peru's congress has agreed to vote on the law's possible repeal - on the condition that protesters unblock roads and suspend demonstrations.
State of emergency
Garcia decreed the law using special legislative powers he was granted to implement US requirements for a free trade pact between the two nations.
A state of emergency had been imposed when protesters occupied oil and electricity plants in the Amazon basin.
Alberto Pizango, leader of the Inter-Ethnic Association of the Peruvian Forest, said: "We're not afraid of the state of emergency."
After talks with Javier Velazquez, the congress president, in Lima on Wednesday, Pizango agreed a 48-hour truce.
About 12,000 indigenous people have been protesting since August 9. Their land is estimated to contain billions of dollars' worth of timber, minerals and oil.
On Sunday, clashes between 800 demonstrators and police left at least four people injured.
The state of emergency, which lasts for 30 days, covers the eastern provinces of Bagua, Utcubamba and Datem del Maranon and the southern district of Echarate.
