Sun Xiang's early free-kick and Gao Lin's superb header gave China a friendly victory over United Arab Emirates at Shenzhen Universiade Sports Center.
Sun blasted home a 30-yard shot with his left foot in the fourth minute after Huang Bowen had earned a free-kick for the hosts, and Gao doubled their advantage 11 minutes later when he met Feng Renliang's cross with a glancing header from 10 yards.
Substitute Eisa Al Marzouqi netted a consolation goal four minutes from the end for the visitors.
The morale-boosting victory helped Spanish manager Jose Antonio Camacho fine-tune his squad before China's crucial clash with Iraq in the third qualifying round for the 2014 World Cup in Brazil.
"We produced spectacular play in the first half with our fast moves while the defensive and offensive lines linked up well with each other," Camacho said. "We should have scored more goals in the first period.
"But I am not satisfied with our performance in the second half. We appeared lazy, running less than our rivals. I believe we can cause a lot of trouble to Iraq if we can repeat our first-half play today."
China will host the 2007 AFC Asian Cup champions on Tuesday - a crucial encounter with both sides on three points in Group A.
"We took time to find our form in today's game, but after all, the result wasn't very important," UAE coach Abdullah Masfar said. "We called some young players for the qualifying game on Tuesday and hope we can achieve a good result then."
