‘Uncertain times’ ahead for the world dairy trade
Meanwhile, the latest update on the world dairy trade from Rabobank has found that we live in uncertain times, perhaps even more so than in recent years.
The election of Donald Trump as the President of the US and the new administration he brings with him, along with uncertain Russian trade relations could have an effect on dairy trade development.
Further uncertainty in the Middle East, Chinese economic performance, Brexit, and the fate of trade agreements such as the Trans-Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (TTIP) can also all have a major effect on dairy trade development, it contends.
