US president Donald Trump has just removed the travel ban he imposed on Chad last year.

"Chad has improved its identity-management and information sharing practices sufficiently to meet the baseline security standard of the United States," said the White House in a statement.

"Chad is pleased to be removed from the list of countries whose nationals are banned from entering the United States, and hopes to further strengthen the strategic partnership and cooperation between the two countries," said foreign minister, Cherif Mahamat Zene in a tweet.

The central African country was put on the controversial list last year because, according to officials, it had "significant" terrorist presence in its borders and was not "adequately" sharing security-related information with the Americans.

Citizens from countries such as Somalia, Libya, Iran, Syria, Yemen, North Korea and Venezuela are still banned from entering the US.
