In 1961, Sweden opened its first resident embassy in Monrovia, reflecting its growing economic and political interest in the region, particularly linked to its investment in LAMCO, a major iron ore mining project.

On 3 October 1958, Sweden's ambassador to Portugal, Knut Richard Thyberg, was appointed as envoy extraordinary and minister plenipotentiary to be accredited in Liberia as well.

[7] Sweden maintained an embassy in Liberia primarily due to its investment in the Liberian American–Swedish Minerals Company (LAMCO), which mined iron ore from 1963 to 1989.

This investment was the largest Swedish commercial project in Africa during the Cold War, blending industrial and political interests.

[8] Between 1955 and 1965, Swedish foreign policy strongly supported LAMCO, combining industrial and diplomatic efforts to protect its operations and boost Sweden's global prestige.

The embassy in Monrovia, established in 1961, managed these interests and portrayed LAMCO as a development-focused initiative, enhancing Sweden's image as neutral and progressive.

While the ambassador to Liberia was primarily based in Stockholm, the embassy in Monrovia was headed by a junior diplomat who managed day-to-day operations.

The ambassador handled Liberian affairs remotely, with periodic visits to Monrovia, focusing on maintaining bilateral relations and overseeing residual Swedish activities in the country.
