chile has denounced cuba

Cuba sends economic aid to the Chilean rebels.
Cuba begins to erect oil wells in Colombia, along with factories for processing the oil into plastics and fuel. New housing is built and farms are enlarged as well.
Cuba also modernizes Colombia's military forts and opens recruiting into the Cuban army to Colombian citizens, although it is not compulsory.
Heavy naval guns designed for the
Granadero class battleship are also installed in coastal fortifications so that Colombia is no longer as hilariously defenseless navally as it previously was, however this concept is also adopted in Cuba so that the nation no longer needs the direct support of its navy to have a solid coastal defense.
Trade docks in Colombia are expanded thoroughly and a few military docks begin construction as well.
