CAMPLUX, France — Camplix, the French appliance maker, will sell its entire line to a Chinese company for about $1.3 billion, a source familiar with the matter said Wednesday.

The Chinese-listed company, Camplx, has been under pressure to buy up more of its U.S. and European brands after U.K. and French regulators banned its sale of consumer electronics products made by its rivals.

Camplx has already agreed to sell its brands including the water heater recycling business and the refrigeration and cooling business to a consortium of Chinese companies including the state-owned China General Chemical Corporation, according to the source, who asked not to be identified because the matter is private.

The group is also planning to buy Camplax’s appliance manufacturing business.

The sales will give Camplox the ability to sell in China, where Chinese buyers account for roughly two-thirds of the market for U.M.S.-made appliances, according a person familiar with discussions with Chinese officials.

China is expected to buy about one-third of Camplxs market by the end of 2020, said the person, who requested anonymity because the company was not authorized to speak to the media.
