China has leverage on Iran and Tehran will find it difficult to explain if it does not honor the agreement signed with Saudi Arabia in Beijing, a Saudi official said on Wednesday.
Iran and Saudi Arabia agreed on Friday to re-establish relations after years of hostility following talks in China.
The official, who declined to be named, said China is in a unique position as it enjoys exceptional relations with both Iran and Saudi Arabia.
The most difficult topics in the talks with Iran were related to Yemen, the media, and China's role, the official said.
