The Blue Line: A CGTN Documentary on UN Peace Missions

The Blue Line runs 120 kilometers across southern Lebanon. It is not a border, but a fragile withdrawal line, where peacekeepers once stood, and where some fell.

In July 2006, four unarmed UN observers lost their lives there. One was Chinese Major Du Zhaoyu. To this day, his mother says her son is “on duty” to deal with her grief.

Irish Commandant Pat Dillon, then with Team Sierra, created a video to honor his fallen colleagues. He had been evacuated just before the fateful day. “We feel cheated that you were taken from us so young.”

Lebanese interpreter Majid Monzer also worked with Du. “Many times we thought perhaps today was our last day, but we kept going because we love peace. This vest showed we belonged to UNTSO. But sadly, it didn’t save every life.”

In November 2024, just four days before a ceasefire, an airstrike struck Majid’s village. He lost his wife and his right leg was injured.

Two decades on, Du inspires a new generation. Xue Guiqing is a Chinese military observer now stationed in the same area along the Blue Line. “When I saw his smiling face in a photo, it felt as if he were looking at me. In that moment, I felt a sense of legacy, responsibility, and conviction.”

Her team leader, Norwegian Captain Yorgen Paul Lycle, believes peace remains elusive because the world fails to invest enough in it.

That issue looms large today. In August 2025, the UN Security Council voted to end the mandate of the United Nations Interim Force in Lebanon (UNIFIL) by 2026. But UNIFIL Force Commander Aroldo Lázaro Sáenz insists the role of peacekeepers is still vital. “We made the decision to remain even during the height of the conflict, because this was the right thing to do. This is our duty.”

Resources are limited; mandates are constrained. Yet many argue peacekeeping remains indispensable. As South Africa’s Defence Minister Matsie Angelina Motshekga says, “It’s a very costly exercise, budgets are very low—but war is even more costly.”

The Blue Line is grim reminder of where lives were lost and where others still serve. In a time of doubt, the world must ask: Can peacekeeping remain the best tool we have to defend the dignity of peace?
