Chinese Vice Foreign Minister Zhang Ming was currently in Saudi Arabia and would travel on to Iran, ministry spokeswoman Hua Chunying told a daily news briefing.
"We hope the situation in the Middle East can move in the direction of amelioration," Hua told reporters, according to Reuters.
Tension between Iran and Saudi Arabia has spiraled since the execution of prominent Shiite cleric Sheikh Nimr al-Nimr in Saudi Arabia.
"We hope that all parties can remain calm and exercise restraint and appropriately resolve relevant issues via dialogue and consultation," Hua added.
While relying on the region for oil supplies, China has tended to leave Middle Eastern diplomacy to the other five permanent members of the UN Security Council - the United States, Britain, France and Russia.
But China has been trying to get more diplomatically involved.
The ministry said that Foreign Minister Wang Yi had met the head of the Western-backed opposition Syrian National Coalition (SNC).
Wang told SNC president Khaled Khoja he hoped the SNC would attend peace talks without preconditions, the ministry said in a statement.
China has repeatedly called for a political resolution and warned that military action cannot end the crisis in Syria. Khoja's visit comes two weeks after Syrian Foreign Minister Walid al-Moualem visited China.
