Iran and Syria have sparred at the talks which took place in Vienna on Oct. 30, which also included the U.S., Russia, Turkey and France along with ministers from nine other nations. The talks ended without an agreement.
"In the first round of talks, some countries, especially Saudi Arabia, played a negative and unconstructive role," Abdollahian said. "Iran will not participate if the talks are not fruitful."
