Spurs won 1-0 in Hong Kong thanks to Pape Matar Sarr's long-range strike.
However, Arteta says they end their Asian preseason in good shape, having won their previous two games.
He said, "We had very clear objectives - one, keep developing our preparation and maximise it every single day to get to a really high level and compete in different contexts in those three matches, and the other one was to connect with our people to get to know again this beautiful culture. We've certainly done both of them despite that tonight obviously we got the result that we didn't want.
"For the three of them and today in particular it showed different demands, different understanding of things that we have to do. I'm very pleased with what I've seen in most of the things that we've done but we missed something you know in certain moments, that preciseness, that moment that unlocks the result and the moment to turn the result away and win the match but in terms of attitude, the desire, level of organisation in the team, it was great and we have to continue to elevate a little bit all the individual aspects."
On his squad is coming together this preseason, Arteta was upbeat.
He said, "I'm very positive, everything that I've seen in the last 10 days gives me a lot of encouragement and we're ahead of what I was expecting in many areas. Even though tonight's result gives you a taste, I think that is going to be very positive as well.
"To realise the margins that winning or not winning have to be controlled as well and again, we go again. We'll start on Monday again with two great games at the Emirates to finalise the preparation and be ready for Old Trafford."
