A first-half double from Guangzhou striker Gao Lin and a third from Liao Lisheng, either side of Lee Donggook's solo effort, settled a flowing game and lifted the Chinese champions three points clear in Group G. Elsewhere, Uruguay international Forlan opened his account for Japan's Cerezo Osaka in their 4-0 win over Thai champions Buriram United, and Melbourne Victory got the first win of their campaign.
In the clash between the top two teams in Group G, Gao was only handed a spot in the Guangzhou starting line-up after Muriqui, last season's top-scorer in the competition, was injured in the pre-match warm-up. And the China international took full advantage, opening the scoring at the Guangzhou Tianhe Stadium after 18 minutes with a close-range finish before deftly heading his side 2-0 ahead two minutes later.
Jeonbuk, who have met Guangzhou in the group stage in each of the past three seasons, pulled a goal back before half-time through skipper Donggook, who pounced on the rebound after his own header hit the post. But the hosts restored their two-goal cushion just after the hour-mark when Liao Lisheng flicked home a cross by influential Italy midfielder Alessandro Diamanti to make it 3-1.
In Group E, Forlan netted his first goal in five domestic and Asian games for new club Cerezo Osaka to round off a straightforward win for the home side against Buriram. Yoichiro Kakitani grabbed his third goal of the tournament after only four minutes and Takumi Minamino struck twice before Forlan, ex-Manchester United and Atletico Madrid, scored in stoppage time.
Steelers hold Shandong
Chinese side Shandong Luneng squandered an opportunity to open up a three-point lead after they allowed ten-man Pohang Steelers to battle back from two goals down for a 2-2 draw in Korea Republic. The match began disastrously for the home side, who had Shin Kwanghoon sent off for deliberate handball and then saw Vagner Love tuck away the resulting penalty after 13 minutes.
Another handball ten minutes later saw Shandong awarded another penalty and Love once again converted for his fourth goal of the tournament. But Pohang fought back with captain Kim Taesu reducing the deficit in the 32nd minute before Kim Seungdae levelled the scores with 13 minutes remaining. Both sides now have five points, one more than Cerezo.
In Doha, Qatar's Lekhwiya defeated Saudi Arabia's Al Ittihad 2-0 to jump to second spot in Group C on goal difference. Urguguay-born Sebastian Soria opened the account in the 22nd minute and South Korean Nam Tae-Hee scored from the spot in the 73rd minute after Luiz Martin was brought down by Hamad al-Montashari to give Eric Gerets' side a 2-0 win.
Lekhwiya trail Al Ain by two points after the UAE giants outclassed Iran's Tractorsazi Tabriz 3-1 with the prolific Asamoah Gyan scoring once in each half and providing the assist for Mohamed Abdulrahman's 38 minute goal. Milad Fakhreddini scored the only goal for the Iranians in the 42nd minute
Meanwhile, in Group A, Iran's Estheglal bounced back twice to hold UAE's Al Jazira 2-2. Al Jazira went ahead in the sixth minute through Abdelaziz Barrada before Ghazi Najafabadi equalized in the 17th. Barrada found the target again in the 56th minute for his second goal, but Hanif Omranzadeh denied Al Jazira victory with his 65th minute strike.
The second Group A match saw Saudi Arabia's Al Shabab edge Qatar's Al Rayyan 4-3. Rayyan led 3-2 at half time after being down by a third minute goal from Majed al-Marshadi, but Rafinha put the issue beyond doubt with two goals early in the second half. Kalu Uche netted twice for the Qatar side.
