The global private equity firm Actis Capital LLP announced on Wednesday that it had made a minority investment in the specialist medical equipment manufacturer Micro-Tech (Nanjing) Co Ltd, a sign of its confidence in the Chinese healthcare industry.

The amount of the investment was not revealed.

"Nanjing Micro-Tech is the number one domestic player in the Chinese endoscopy consumable market," said Meng Ann Lim, head of China and Southeast Asia at Actis. "We see great potential in the Chinese healthcare sector and look forward to working with CEO Leng (Derong) and his team, with whom we share a clear vision for the future of Nanjing Micro-Tech.

"Nanjing Micro-Tech has expanded steadily over the past 12 years. Our partnership with Actis will take us to the next stage, equipping us with a clearer strategy, a world-class management team and new routes for business expansion."

An endoscopy is a minimally invasive medical procedure used to examine the inside of a hollow organ or cavity.

Because of China's aging population, changes in the way people live their lives, increasing incomes and better insurance coverage, the demand for high quality medical products and services has become stronger in both China and the world.

The global endoscopy consumable sector was a $4.4 billion market in 2011 and is expected to reach $7.6 billion in 2017, having a 9.4 percent compound average rate of increase, Actis said.
