Jeonbuk Motors will once again face Cerezo Osaka after the top two in Group G were paired together in the quarter-finals of the AFC Champions League.
Cerezo inflicted Jeonbuk's only defeat in the competition so far - a 1-0 win in Osaka - and will look to once again overcome the Koreans at home before heading to their regional rivals two weeks later.
Al Ittihad will continue their bid for a third Champions League crown when they meet FC Seoul.
The Saudis are the only team to win the competition twice but saw their bid for a hat-trick foiled by Pohang Steelers in the 2009 final.
Last year's defeated finalists Zob Ahan face Suwon Bluewings while fellow Iranians Sepahan play Al Sadd from Qatar.
In the AFC Cup, the tie of the round sees 2009 winners Kuwait Sports Club take on 2010 semi-finalists Muang Thong United.
The Kuwaiti side edged through on penalties against domestic rivals Al Qadsia and face another difficult test in the form of the powerful Thai team.
Elsewhere, Chonburi were handed a daunting challenge when drawn against Nasaf - the Uzbeks have won all seven of their AFC Cup games so far - while Al Wehdat meet Duhok and Persipura Jayapura take on Arbil.
