China and North Korea open a 3,026-meter bridge after leaving it shut for 12 years

Trade between the two countries was growing before the new span carried a vehicle. In the first half of this year it came to about $1.51 billion, up 19.6% from a year earlier ^[8], which puts the first half of last year near $1.26 billion ^[13]. Last year's full-year total of about $2.736 billion was 98.1% of the 2019 level ^[9], so 2019 was about $2.79 billion ^[14]. The first half was about 46% of last year's total ^[15]. If this year keeps that split, full-year trade lands near $3.27 billion ^[16], about 17% above 2019 ^[17]. That projection leaves the bridge out entirely, and a single year's seasonality is thin support for it.

The bridge raises the ceiling. Overland freight had been limited to one two-lane crossing, and the report says that capped volumes ^[3]. China estimates the new four-lane, 3,026-meter bridge can handle up to 20,000 vehicles and 50,000 passengers a day ^[12]. Without a current traffic count for the old bridge, the headroom cannot be sized.

The 12-year delay complicates the warming story. Jung Eun-yi, who heads the Korea Institute for National Unification's division for North Korean research, said: "With Sinuiju lacking the capacity to absorb the traffic, opening the bridge would have turned the city into a mere transit point rather than a growth hub" ^[5]. Sinuiju has since been built out with corporate offices and infrastructure ^[6], though the report did not disclose whether the connecting roads and customs facilities that were officially missing are now finished.

The diplomacy fits the timing. Kim Jong-un stood beside Xi Jinping at the September parade marking the 80th anniversary of China's victory in World War II, passenger rail resumed in March after six years, Wang Yi visited Pyongyang in April, and Xi traveled to North Korea in June ^[7].

Lim Eul-chul, a professor at the Institute for Far Eastern Studies at Kyungnam University, said the bridge "will ease the logistics bottleneck at the aging Yalu River railway bridge and accelerate large-scale customs clearance in both directions" ^[10]. He also said: "It amounts to securing the means to maintain a harder line of severed inter-Korean relations" ^[19].

We think the bridge follows the recovery and does not drive it: trade and diplomacy moved first, and the span is the infrastructure catching up. The counter-thesis is that the 19.6% was the old crossing running at its limit, in which case the new capacity should produce growth well above that pace. A third outcome is Jung's transit point, with Chinese cargo passing through Sinuiju and little left behind. Second-half growth well above 19.6%, measured against the same months a year earlier, would show the cap was binding and our view wrong.
