The French foreign ministry has summoned Pakistan's envoy to protest claims by President Arif Alvi that a French bill cracking down on radical Islam stigmatises Muslims.

Addressing a conference on religion on Saturday, Alvi said: "When you see that laws are being changed in favour of a majority to isolate a minority that is a dangerous precedent."

Specifically referring to the legislation drafted after the beheading of a French teacher by an Islamist radical over blasphemous cartoons, Alvi said: "When you insult the Prophet, you insult all Muslims.

"I urge the political leadership of France not to entrench these attitudes into laws... You have to bring people together -- not to stamp a religion in a certain manner and create disharmony among the people or create bias."

Pakistan was one of several Muslim countries that saw angry anti-French protests in October over President Emmanuel Macron's defence of the right to show profane cartoons.

The country with the second-largest number of Muslims in the world after Indonesia does not have an ambassador in France.

The French foreign ministry said late Monday it had called in Pakistan's charge d'affaires to mark "our surprise and our disapproval (over Alvi's remarks), given that the bill contains no discriminatory element."

- 'Constructive attitude' -

"It is guided by the basic principles of freedom of religion and conscience, makes no distinction between the different religions and applies therefore equally to all faiths," the ministry said.

"Pakistan must understand this and adopt a constructive attitude for our bilateral relations," it added.

The bill adopted by the lower house of the French parliament last week is dubbed the "anti-separatism" bill in reference to Macron's claim that Islamists are closing themselves off from French society by refusing to embrace secularism, gender equality and other French values.

The legislation significantly expands the state's powers to close religious organisations and places of worship if they are found to air "theories or ideas" that "provoke hate or violence towards a person or people." 

It also creates a new crime of "separatism" -- described as threatening a public servant in order to gain "a total or partial exemption or different application of the rules" -- that is punishable by up to five years in prison. 

Pakistan's government has been particularly virulent in its condemnation of Macron's clampdown on radical Islam, which follow a wave of attacks that have killed over 250 people.

Prime Minister Imran Khan in October accused Macron of "attacking Islam" and chosing to "encourage Islamophobia" for defending the right to publish profane cartoons.
