The amount of money involved in these cases reached 4.9 billion yuan ($787 million), and the total number of victims was more than 94,600, the report said. In 2009, a forestry contract fraud case brought economic losses to more than 23,000 people across the country.
The criminals signed fake contracts with victims and made online pyramid sales, convincing people to invest in illegally registered government administrations and international companies, the report said.
Among the cases that have been solved, 24 criminals were from overseas, the report added.
"It was rare to hear cross-border economic cases involving so many victims a decade ago, which might be due to our country's economic development at that time," said Tan Jinsong, a senior judge responsible for handling such cases in the court, at a news conference on Monday.
"Cross-border cases are difficult for judges to deal with and usually bring huge legal challenges for police to investigate, as they are committed from foreign countries which have different legal systems," he said.
