A little-known Asian investor has taken advantage of the ongoing strength of bulker markets to sell a string of ultramaxes connected several years ago to Australian mining tycoon Clive Palmer.

The first in the series of four Chinese-built sisterships changed hands early this year — and at least two others have been sold since then.

In January, several brokers reported that the 63,000-dwt Asia Ruby I (built 2014) was sold to Greek buyers for about $15.5m.
