Apply for a Chinese visa in Kolkata - non-Indian citizen

Hi there,
I am an Irish citizen living in Germany and would like to apply for a Chinese visa. I am planning a long journey across many countries, but will leave my home country outside of the visa validity window (i.e. if I apply for it here it will have expired by the time I get to China). I see in your fee structure there is a section "Citizens of Other Countries" - is this all other countries, or just a select few? Could I apply with my Irish passport? I will be travelling through Kolkata, so if this is a possibility that would be fantastic.
Thank you for your time.
