China on Wednesday said there was no truth to an Iranian media report about a joint military drill involving China, Russia, Syria and Iran.

"The report is groundless," said Foreign Ministry spokesman Hong Lei at a regular press briefing.

The Iranian news agency Fars reported that 90,000 troops and hundreds of ships, tanks and warplanes from the four countries would take part in a land and sea drill in Syria soon.

Russia and Syria have also denied the report.
