China's first national selenium research and development (R&D) center opened Sunday in Wuhan, capital of Central China's Hubei Province.

The center aims to beef up selenium research, standardize the selenium industrial system, upgrade the sector, and offer technical support for selenium-related companies, said Cheng Shuiyuan, director of the center at a press conference.

The center began as a project in September 2018, approved by the country's Ministry of Agriculture and Rural Affairs.

Selenium is an important micronutrient to boost human immune system and reduce the effects of cardiovascular diseases, according to the press conference.

China has a huge demand for selenium-enriched agricultural products because 72 percent of the country's arable land lacks the element.

Hubei's Enshi Tujia and Miao Autonomous Prefecture, however, has rich selenium deposit.
