Do I need to file tax return if I have no income, my husband is a non-US citizen, and we both living in China?

I am a US citizen, I married my non-US citizen husband, registered our marriage in China, we both living in China. I stay at home as a housewife, with no income, do I still need to file a tax return for my husband's income?  I am leaning to no, but please advise.

What if we decide to move to the US one day, will filing my husband's income tax return now help in the future?

Thank you
