Aerial photo taken on Jan. 16, 2019 shows the Piraeus port, Greece. In 2016, China's COSCO SHIPPING purchased a 67-percent stake in Piraeus port, which was then struggling. In just two years, Piraeus' performance has soared. Its container throughput has increased from 880,000 TEUs in 2010 to 4.9 million TEUs in 2018, ranking second among all Mediterranean ports.
