The Angara River is a tributary of the Yenisei River.
Yenisei is longer
The River Yenisei primarily flows through Mongolia and Russia, but its source is located in the Tuva Republic, near the border with Mongolia. A small portion of its watershed extends into China, but the river itself does not flow through Chinese territory. Therefore, while it has some connection to China, the Yenisei River is not located in China.
The Yenisei River starts in Asia and ends in Siberia, into the Arctic ocean.
