- Beijing will pile up debts as it tries to revive China's economy, according to Fitch.
- The ratings agency cut its outlook for China to negative on Wednesday.
- Policymakers are also battling faltering growth and an ongoing property-market crisis.
Fitch Ratings has cut its outlook for China, adding to the gloom surrounding the world's second-largest economy.
Beijing is likely to pile up more debt as it tries to "transition away from property-reliant growth to what the government views as a more sustainable growth model," the credit ratings agency said. It cut its outlook from "stable" to "negative," but maintained its overall rating at "A+."
