How to improve this sentence?

It must be noted that there is presently an intensely increasing collusion between regional terrorists and drug-related criminals, which vindicates a systematic campaign to handle both of them through anti-terrorism and drug-banning.

It's my version of translation from a Chinese article. Could you please tell me how to improve it?

Thank you.

This is the key version:

What merits caution is that there is a growing tendency of terrorists and drug criminals colluding with each other in the region. Therefore, counter-terrorism and anti-narcotic efforts should be integrated with a two-pronged approach.
