The home side was the better team on the night in the 0-0 draw, creating more chances than their Chinese opponents but were unable to capitalise.
Nagoya coach Dragan Stojkovic said his side were good but not good enough.
"The game was very good, with good pace, but at the same time very tough," said Stojkovic.
"Beijing is a good, organised team, and they played defensively very well. They are very dangerous in counter-attacks. It was important we didn't concede a goal.
"The result was 0-0, which is not so bad especially considering our hard schedule. We played our previous game in Yamagata in very bad and extremely difficult conditions.
"We always look for scoring and winning the game. Today, we show our attacking mentality, even after making our substitutions. I'm satisfied with our efforts and our mentality. I think we deserved a little bit more than a draw today.
"Collecting four points from two games, it's absolutely okay. It's good. I think we have showed that we are able to play good football and not lose the game."
