Aircraft deviating for weather was issued a right turn. The pilot had to refuse the clearance due to weather. The pilot observed traffic on their TCAS descending below them.

Narrative:
Level at 21;000 feet on the arrival; aircraft X took a 125 degree heading to deviate for weather. We were shooting a narrow gap between two radar returns. We had been on this heading approximately 20 miles; and were just penetrating the gap; when ARTCC issued a turn 30 degrees to the right; without explanation. We replied; 'unable'; as to make that turn at that point would put us directly into the cell on our right that we were avoiding. At this time; we also observed traffic on our TCAS; approximately 10 miles distance at our 11 o'clock; 200 feet below our altitude and descending. Approximately 30 seconds elapsed; as we watched the TCAS traffic descend below our altitude. The next transmission we received from ARTCC was; 'I know you're deviating for weather; but when I tell you to turn; it's important.' we chose not to engage in further discussion of this matter over the radio. Clearing the weather; we proceeded direct to [fix]; and completed the rest of the arrival; approach and landing normally.
