Trade between Brazil and Turkey has reached $5.9 billion, and the presidents of the two countries say that figure could grow quickly. That was the upshot of a meeting between President Luiz Inácio Lula da Silva of Brazil and President Recep Tayyip Erdogan of Turkey, held during Mr. Lula’s visit to Turkey for the 31st U.N. Climate Change Conference, known as COP31, which opens Nov. 11.

Mr. Lula described the meeting in a post on X. “We talked about the growth of our bilateral trade, which has already reached $5.9 billion, and we noted that it’s possible to expand that amount quickly,” he wrote. He said the two leaders had expressed interest in strengthening ties between their countries. He added that he had stressed Brazil’s interest in “establishing a more robust partnership in the area of defense with Turkey.”
