He said China encouraged dependency, utilised corrupt deals and endangered its natural resources.
U.S. budgetary priorities tell a different story.
U.S. Secretary of State Rex Tillerson said millions of people were facing life-threatening food insecurity and malnutrition as a result of ongoing conflict or prolonged drought in the countries.
In an administration that has often struggled for coherence in its foreign policy, and which lives by the maxim of America First, it would be unrealistic to expect Secretary Tillerson to deliver a transformation in the relationship between U.S. and Africa.
He was speaking at George Mason University in Virginia on the eve of his first official trip to Africa.
More than $110 million is for affected populations in Somalia and over $128 million for millions in Nigeria and the Lake Chad region.
Tillerson also said USA and African leaders "must work to find long-term diplomatic solutions" to regional conflicts "that cause so much human suffering."He announced the United States will give $533 million in additional aid to alleviate starvation and other needs caused by conflicts in Ethiopia, the Lake Chad Basin, Somalia and South Sudan".
Tillerson said he has made many trips to Africa before, in his former career as an oil executive. The day before Tillerson's departure, about 100 protesters gathered outside Tillerson's office in Washington chanting against the government.
In Djibouti, China's development of its first overseas military base just a few miles away has been cause for concern for the US, illustrating the military side of a broader competition between the USA and China playing out across the continent.
Tillerson contrasted the United States' work on the African continent, which he said promoted "sustainable growth", with that of China, which recently pledged US$124 billion (RM484 billion) for its plan to expand links between Asia, Africa, Europe, and other places.
In Djibouti, home to the only permanent USA military base in Africa, China's development of its first overseas base just a few miles away has been cause for concern for the United States, as is African nations' growing indebtedness to Beijing, which is building infrastructure across the continent.
Tillerson will also visit Kenya, where the political system is in turmoil over disputes related to President Uhuru Kenyatta's re-election. But word emerged Tuesday that his administration would start approving elephant trophy importing on a "case-by-case" basis.
According to him, these additional funds will provide emergency food, nutrition assistance, and other aid. About $184 million was destined South Sudan and $110 million for Somalia amid conflicts in both countries.
