Although China has ended subsidies for energy-saving home appliances, Embraco, the world's leading high-efficiency refrigeration compressor maker, said it will invest more in greener products for the country's "increasingly demanding" customers.

Roberto Campos, president of the Brazilian company, which supplies almost all major refrigerator manufacturers, said the new investment reflects the belief that China will enjoy the fastest customer growth in the coming years of all of his company's six operations globally.

Campos, who didn't reveal the size of the investment, said his company is evaluating all the opportunities this year to gain a full picture of how to further its growth in China, which is seen as Embraco's cornerstone for overseas production and new technologies.
