The bilateral agreement, signed on 6 May 2015, between the European Union and the United Arab Emirates, allows citizens of UAE to stay in the Schengen area without a visa for up to 90 days within any 180-day period.

Nationals of other countries (resident in the United Arab Emirates): There is a common list of countries whose citizens must have a visa when entering the Schengen area and those whose citizens are exempt from that requirement:  https://ec.europa.eu/home-affairs/sites/homeaffairs/files/what-we-do/policies/borders-and-visas/visa-policy/apply_for_a_visa/docs/visa_lists_en.pdf)

Please note that even if you are a citizen of a country whose citizens are generally visa-free, the visa-free regime applies only to short stays up to 90 days of non-profit nature in the Czech Republic. If your purpose of stay in the Czech Republic is short-term employment or another paid activity, you still need to apply for a Schengen visa.

Holders of residence, re-entry permits and long-term visas  in a Schengen State do not need a visa to enter the other Schengen States. Such visits are of maximum 90 days in any 180-day period.
