In the painting, one of 100 on the same theme, China’s president, Xi Jinping, appears as he has in all the previous ones: a larger-than-life figure who commands attention because of the goodies he has brought with him.

Decked in a flowing white garment, Mr. Xi is surrounded by a crowd of black men — some with bald heads, others with unkempt beards — all reaching out for the dollars leaking out of a briefcase.

The work of a Kenyan artist and painter, Michael Soi, the collection “China Loves Africa” questions the guiding principles of Beijing’s engagement in Africa, scrutinizes the role of leaders on both sides in shaping the relationship and examines the consequences for ordinary citizens. The bright acrylic paintings on canvas have proven popular and polarizing and have offered a creative and complex approach to China-Africa relations.

But on Jan. 2, after six years and 100 pieces, Mr. Soi said he was finished with the series, having drawn enough attention to the issue.
