British based anti-persecution charity Christian Solidarity Worldwide is joining Impulso 18, Open Doors-Mexico and Voice of the Martyrs-Mexico in calling for action.
CSW says it's concerned over a rise in freedom violations recently.
The charity says members of minority religious groups are regularly subjected to attempts at forcible conversion and participation in majority religious festivals, exclusion from state run schools, barred from access to electricity, water and farmland, the destruction of religious buildings, violence, and in the worst cases, forced expulsion.
Chief Executive Mervyn Thomas said, "It is unacceptable that in a modern and diverse democracy like Mexico these types of serious religious freedom violations continue to take place on a regular basis, affecting thousands of men, women and children, with no adequate response from the Mexican government at any level.
"We call on members of the international community, including the European Union and the United States, to actively monitor the religious freedom situation in Mexico and to hold the government to account under its obligations in the treaties to which it is party, including the International Covenant on Civil and Political Rights and the International Covenant on Cultural, Social and Economic Rights - as a matter of urgency.
Despite 95 per cent of the population claiming to be Christians, Mexico is a secular state.
