Eager to feed its growing energy appetite, China’s worldwide buying binge for oil and other energy assets is spreading to North and South America.

Big deals: Earlier this month, reports said PetroChina is close to buying an old refinery on Aruba owned by American refining giant Valero. China is also said to be interested in building a pipeline to carry 300,000 barrels a day of Colombian oil to the Pacific Coast, according to a recent Eurasia Group note.
