Burma's state-run "New Light of Myanmar" daily reports that the plants will be built by the China Power Investment Corporation in Kachin state along the Burma-China border.
The paper said the hydroelectric plants are expected to generate more than 13,000 megawatts of power.
It said the seven plants will generate more power than Burma's biggest hydro power project, a joint venture between the Burmese government and a Thai energy firm on the Salween River.
Thailand's Thai MDX Group has invested six billion dollars in the joint project. There were no cost figures for the Chinese project.
