Senegal is believed to have significant deposits of natural gas along its border with Mauritania at a time when Germany and other European countries are trying to reduce their dependence on importing Russian gas.

"We have begun exchanges and we will continue our efforts at the level of experts because it is our wish to achieve progress," Scholz said at a joint news briefing with Senegalese President Macky Sall.

The gas project off the coast of Senegal is being led by BP, and the first barrels are not expected until next year.

This week's trip marks Scholz's first to Africa since becoming chancellor nearly six months ago.

Two of the countries he is visiting -- Senegal and South Africa -- have been invited to attend the Group of 7 summit in Germany at the end of June.

Participants there will try to find a common position toward Russia, which was kicked out of the then-Group of Eight following its 2014 seizure of Crimea from Ukraine.

Leaders at the G-7 summit also will be addressing the threat of climate change. Several G-7 countries, including Germany and the United States, signed a 'just energy transition partnership' with South Africa last year to help the country wean itself off heavily polluting coal.

A similar agreement is in the works with Senegal, where Germany has supported the construction of a solar farm.

German officials also said Scholz will make a stop in Niger, a country that like its neighbours has long been battling Islamic extremists.

Earlier this month, the German government backed a plan to move hundreds of its soldiers to Niger from neighbouring Mali.

The development comes amid a deepening political crisis in Mali that prompted former colonial power France to announce it was withdrawing its troops after nine years of helping Mali battle insurgents.

Germany, though, will increase its participation in a UN peacekeeping mission in Mali, providing up to 1,400 soldiers.
