Kuwait (Western Asia) and Brazil (South America) are separated by **half the planet**. There is no contiguous land corridor. The question likely implies a **great-circle flight path** or **maritime route**.
Countries intersected by a **direct great-circle line** (Kuwait City → São Paulo ~12,800 km):
If tracing a **land+sea route** (historical trade / modern shipping):
The source's list (Saudi Arabia, Qatar, Bahrain, UAE, Oman, Yemen, Ethiopia, Kenya, Tanzania, Mozambique, Madagascar, South Africa, Namibia, Botswana, Angola, DRC, Zambia, Malawi, Zimbabwe, Argentina) describes a **meandering African coastal tour**, not a direct "between" path. Argentina borders Brazil; the others are far off any direct line.
Bottom line: No countries are "between" them in a geographic sense — only oceans and a choice of routes.
