Chad’s President Mahamat Idriss Deby announced that his country will suspend the issuance of visas to U.S. citizens in response to the Trump administration’s decision to ban Chadians from visiting the U.S.

President Donald Trump on Wednesday resurrected a hallmark policy of his first term when he announced the visa ban on 12 countries, including Chad, accusing them of having “deficient” screening and vetting, and historically refusing to take back their citizens who overstay in the United States.

The new ban targets Afghanistan, Myanmar, Chad, the Republic of Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen.

There will also be heightened restrictions on visitors from seven other countries in the new travel policy, which takes effect Monday at 12:01 a.m. In a Facebook post, Chad’s president said he is directing his government to suspend visas to U.S. citizens “in accordance with the principles of reciprocity.”

The Republic of Congo calls the ban a mistake. The new travel policy has triggered varied reactions from African countries, whose countries make up seven of the 12 countries affected by Trump’s outright visa ban, with some exemptions.

In the Republic of Congo, government spokesperson Thierry Moungalla said he believes the country was among those affected because of a “misunderstanding” over an armed attack in the U.S., with the perpetrators mistakenly to be from the Republic of Congo.
