COPENHAGEN, Denmark (AP) — Norway's prime minister warned Brazil's president on Friday to curb deforestation in the Amazon or Norway will reduce its financial contribution to the project this year.

The announcement comes as the Amazon and Atlantic rainforests are being cut down at the fastest rate in nearly a decade, according to official Brazilian figures.

Norwegian Prime Minister Erna Solberg said Norway's more than $1 billion contribution to the so-called Amazon fund is "based on results," Norway's NTB news agency said. Since 2001, Norway has donated billions to encourage the conservation of forests.

"If preliminary figures about deforestation in 2016 are confirmed, it will lead to a reduced payout in 2017," Solberg said after meeting with Brazilian President Michel Temer in Oslo.

Temer praised Norway's contribution to the fund but declined to take questions from media after he and Solberg had made their statements.

"This contribution has enabled us to make a more effective impact to avoiding deforestation," Temer said, according to NTB.

Temer said Monday he had vetoed legislation to reduce the size of protected environmental reserves. However, the apparent victory for environmental groups most likely will be short-lived, as Brazilian Environment Minister Jose Sarney Filho is working on similar legislation.

The legislation passed by Brazil's Congress last month would have converted around 1.4 million acres (566,000 hectares) of protected land into areas open to logging, mining and agricultural use.

However, last week, Filho announced plans to create a new expedited bill that would convert 1.1 million acres of protected land to other uses.

Last year, deforestation in the Amazon jumped 29 percent over the previous year, according to the Brazilian government's satellite monitoring. That was the highest rate since 2008.

Before his meeting with Solberg, Temer was met by protesters holding posters reading "Stop rainforest destruction" and "Respect indigenous peoples' rights" as he arrived at the prime minister's office in Oslo.
