Barcelona players will have "DR Congo - Heart of Africa" emblazoned on the back of their training shirts from the start of next season, after the top Spanish football team agreed on a four-year deal with the central African country.

The partnership will reportedly cost the Democratic Republic of Congo 44m euros ($50m; £38m), although the club has not disclosed the amount it will receive.

The arrangement has faced criticism from some Congolese who have questioned their government's priorities, especially as its domestic football league has been plagued by chronic underfunding for years.

But the authorities have defended the agreement, saying that it will help raise the profile of the country.

As part of the deal, Barcelona's Camp Nou stadium will host what the club called an "immersive exhibition... to showcase the cultural diversity and sporting tradition" of DR Congo.

The country's Sports Minister Didier Budimbu told BBC Focus on Africa that the agreement includes a training camp for 50 young Congolese players and 10 coaches.

Barcelona says it will also run camps for children across a range of sports, including basketball, handball and roller hockey.

DR Congo has signed similar deals with Italian side AC Milan and French team AS Monaco. Last month, Budimbu described them as part of a strategy to "reposition" DR Congo as a leader in tourism and investment opportunities.

Since 2018, DR Congo's regional rival Rwanda has had a sponsorship deal with English side Arsenal promoting tourism in the country with the slogan "Visit Rwanda" on the sleeves of the players' shirts. French team Paris St-Germain and German side Bayern Munich have similar deals.

These have also come under fire, especially recently as Rwanda has been accused of backing rebels in DR Congo in a devastating conflict in the east, which it denies.

In February, DR Congo Foreign Minister Thérèse Kayikwamba Wagner wrote to the clubs questioning the "morality" of the arrangement.

The Rwandan government dismissed the accusations of sports-washing as a "distraction".

In June Rwanda and the DR Congo signed a peace deal aimed at ending decades of the devastating conflict.

In 2023, a deal that South Africa's tourism board pursued with Tottenham Hotspur did not come to fruition after complaints from the public.

Despite similar noises from some quarters in DR Congo, this arrangement has gone ahead.

Since the onset of Covid-19, the country's national football league has struggled, mostly for lack of funding for travel across the vast country.

Some critics have expressed concern that the European deals could overshadow the conflict in the east and the government's troubling human rights record.
