Beijing, May 22 - An Indian trader has gone missing in China's commodity market hub of Yiwu, officials said today, as Beijing criticised India's second trade advisory warning that it would affect normal bilateral economic exchanges.

Indian embassy officials here told PTI that an Indian trader from Mumbai, who was based in Yiwu for a while, was reported to have been missing by his relatives.

His name has been withheld by the embassy for security reasons.

He was reported to have gone missing on May 19 and his mother from Mumbai had contacted the Indian mission and complained that he was not seen since then.

This was the second such incident in recent months.

Two Indian traders Deepak Raheja and Shyam Sunder Agrawal, who too had gone missing, were later found to have been abducted by local Chinese traders for non-payment of dues to the supplies bought by their company, which was owned by a Yemenese national who reportedly fled from China.

The two complained of torture and were released from the illegal detention in January after India officially took up their case. The two are currently based in Shanghai and fighting their case with the aide of the Indian Consulate there.

Meanwhile, Chinese Foreign Ministry spokesman Hong Lei sounded critical of the new advisory issued by Indian embassy here that warned Indian businessmen that they could be drawn into a lengthy and questionable judicial process if they run into problems with traders in Yiwu.

"China always safeguards the legitimate interests of foreign businessmen, including Indians," he told a media briefing here when asked about the advisory as well as the second case filed against the two Indian traders. PTI
