BEIJING - Chinese companies whose tainted milk products sickened nearly 300,000 children and were blamed in the deaths of six will likely pay US$160 million in compensation to victims' families, a newspaper said Tuesday.

Details of the compensation plan came shortly after trials began for 15 people on charges related to the production and sale of melamine, an industrial chemical added to milk to falsely boost protein readings in quality tests.

China Daily reported the 22 companies blamed in the scandal will make a one-time $131-million cash payment to victims.

The remaining $29 million would cover bills for lingering health problems, the paper said, citing an unnamed source from the China Insurance Regulatory Commission.

Details in the report roughly correspond to figures provided this month by lawyers seeking to sue the companies involved, who said most children who suffered kidney stones would get $290, while sicker children would be paid $4,380.

Families of children who died will each get $29,000, China Daily said.

At least six babies died and 294,000 other children suffered kidney and urinary problems from drinking the baby formula made from the contaminated milk.

The compensation plan - which was originally announced Saturday - and the trials of those blamed for the contamination appear to signal authorities hope to end what was widely seen as a national disgrace highlighting widespread problems with food safety and corporate and governmental malfeasance.

At least four of the suspects on trial could be given the death penalty, Xinhua News Agency said. The status of the trials were not known and Xinhua said verdicts would be announced on an unspecified "selected date."

The four face charges of endangering public safety for allegedly producing a mixture of melamine and malt dextrin, a food additive made from starch, that they marketed to milk producers, state media reports said.

Between November 2007 and August 2008, they sold it to milk producers - including Sanlu Group Co., the dairy at the heart of the scandal - for a total of $180,000, the reports said.

Xinhua said the other five on trial are charged with producing and selling toxic food but did not give other details.

The discovery of melamine in dairy exports such as chocolate and yogurt triggered a slew of product recalls overseas.

The first trials in the case began on Friday for six men, also charged with making and selling melamine.

Hearings were held Monday in the northern city Shijiazhuang, where Sanlu is headquartered, along with three other cities in surrounding Hebei province, said Xinhua and state broadcaster CCTV.

Sanlu's chairwoman and general manager, Tian Wenhua, is scheduled to go before a Shijiazhuang court Wednesday.
