Boris Liedtke has returned to Singapore as Deutsche Asset Management's chief executive officer for Asia-Pacific ex-Japan.

He will be responsible for implementing Deutsche AM's strategy in the region, managing its relationships with regulators and governments, and chairing the firm's Asia-Pacific regional management committee.

Liedtke reports to Mark Cullen, Deutsche AM's New York-based global chief operating officer, who had been acting Asia-Pacific head since Ed Peter moved on earlier this year. In April, Peter left with several colleagues to set up Duxton Asset Management, a specialist investment firm in Singapore that focuses on agriculture and emerging markets. Deutsche AM also saw the departure of Philip Levinson in July.

Liedtke has spent the past 15 years with Deutsche Bank, including eight years in Asia. He helped establish new business operations for Deutsche Bank in the region while based in Hong Kong and Singapore. Most recently, he held several COO roles within Deutsche AM and DWS Investments (another Deutsche subsidiary) in both Frankfurt and New York.

Deutsche AM is Germany's biggest fund manager with a global AUM of $646 billion as of June 30 and $20 billion of assets invested in Asia as of September 30.
