Two Chinese men have been kidnapped in the Philippines, the Philippine military said on Tuesday, becoming the latest victims to be abducted in the country's troubled south.

Six armed men marched the pair, known locally as James Lou and Jampong Linyuan Kai, out of their house on Mindanao island and into a van waiting outside late on Monday, according to local military spokesman Captain Albert Caber.

The Chinese General-Consulate in Cebu on Tuesday told China Daily that it has received reports from local police, and the consulate's staff members are verifying the relevant details.

A spokesman for the Chinese embassy in Manila also told AFP it was trying to confirm the kidnapping.

The two Guangdong natives had lived in the town of Kabasalan for almost two years, buying manganese ore from local miners, said Caber, quoting local authorities.

The consulate's consular district includes 33 provinces in Visayas and Mindanao of central and southern Philippines.

"The kidnappers must have noticed they had a lot of money so they thought it was a good idea to abduct them," Caber said.

Police found the suspects' van abandoned and on fire a short while later, but the two victims and their kidnappers had disappeared.

Caber said he believed the gunmen may have destroyed the vehicle to cover their tracks.

There has been no ransom demand nor has anyone claimed responsibility, but Caber said the crime was likely the work of former Muslim guerrilla-turned-bandit leader Waning Abdulsalam.

"It looks like his group, and they are the main gang operating in the area," Caber added.

Islamic extremists and former Muslim rebels in the southern Philippines have often resorted to kidnappings to raise money, targeting both locals and foreigners, who are perceived to be wealthier.
