The Chinese presence on Dominica is astounding. there are crews of Chenese workers all over the island, working on roads and other infrastructure. There are secret arrangements between the government of Dominica and China that local newspapers constantly refer to and demand information about. "No" says the government. "It's a state secret."
Remember, Dominica has a tiny population, about the same as a small US town (78,000). Qualified and competent leadership is hard to find. More than once corrupt politicians there tried to sell off huge sections of the island to foreign interests. Dominica is also poorer than any other nation in the Western Hemisphere, excepting Haiti. Cuba and China provide most of the assistance they get, Cuba technical and medical, China a vast infusion of cash and construction workers.
China is investing heavily in Dominica. Their embassy is huge. Their presence is remarkable. They recently built a bridge into Roseau with those gold Chinese liondogs as decorations. Local people painted them with black tar. They were cleaned immediately. A lot of mysterious developments in Dominica as China's star rises and America's sun sets.
Building a larger airport will require removing at least one mountain. It may yet happen. There is talk of building fish processing plants.
