What Indicators/datasets Would I Look For To Analyze Bilateral Trade?

Hello everyone, I hope this is the correct place to ask.

As part of a university project I am looking at how Dutch trade with both Japan and China has been impacted positively / negatively by the Japan-China territorial disputes. I want to just get a very general overview of how the trade has varied over time.

But for the life of me, I can’t figure out what indicators or datasets to use for something so seemingly simple. I found BACI and UNCOM, but don’t know which one would be most useful or if they are even relevant.

Thank you very much in advance, and warm regards.
