Marine Le Pen pictured with Chad's president Idriss Deby on Tuesday
The Front National boss and head of state discussed continued cooperation in the fight against Islamist militants in the region, with Chad home to France’s 4,000-strong West African anti-terrorism operation, known as Barkhane.
The presidential candidate said: "We have of course discussed the cooperation between France and Chad in the fight against terrorism.”
She added that the two leaders had also discussed Libya and condemned France’s role in helping remove former dictator Mummer Gaddafi from power, which she branded "a serious mistake… with serious consequences."
Le Pen is set to address French troops during her two-day visit, which is seen as a commitment to her pledge to stop Islamic fundamentalism before it reaches French shores.

France has suffered terrible atrocities at the hands of Islamic extremists in recent years, including the Paris attacks in November 2015 and the Bastille Day killings in Nice last July.
The Front National leader has pledged to increase defence spending and curb immigration in a bid to reduce the possibility of further attacks.
However, her visit to Chad has been met with criticism by the country’s opposition parties.

In a statement, the Patriotic Rally of Renewal (PRR) opposition said: "[Marine Le Pen], who is xenophobic and even fascist, is undertaking the visit under the pretext of meeting [soldiers] of Operation Barhkane, but the real reasons are elsewhere.
"Marine Le Pen is coming to Chad, just like the other French political elites, to seek funds for her campaign from the Chadian authorities, who are known for their generosity towards the latter.
"Chad is no longer a French colony and the Chadian people must break ties with the neo-colonialist policy of France and take its destiny in its hand.”
Le Pen also traveled to Lebanon in February this year to develop a better understanding of the Syrian crisis.
She called for closer cooperation with Syrian president Bashar al-Assad and encouraged better ties with Russian president Vladimir Putin.
