French President Emmanuel Macron on Friday toured one of the world's oldest irrigation systems alongside Chinese President Xi Jinping as he continued his three-day visit to China.

The irrigation system, originally built around 256 BC, is still in use today and is a significant example of ancient water conservancy engineering.

Dujiangyan's essence lies in harnessing nature's forces through division and guidance, rather than blockage, using minimal intervention to achieve flood control, irrigation, and sediment management.

During the visit Xi told Macron the Chinese feat of engineering could "be extended to a lot of areas" including politics.

Macron arrived in China on Wednesday for a three-day state visit focusing on trade and diplomatic talks as the French president seeks to enlist Beijing in pressuring Russia toward a ceasefire with Ukraine.

Macron initially met with Xi on Thursday morning as part of the visit where the pair pledged deeper cooperation on global issues like the war in Ukraine and trade.
