China’s economic growth sank to a new multi-decade low in 2019 as Beijing fought a tariff war with Washington, but forecasters said an interim U.S.-Chinese trade deal might help to revive consumer and business activity. The world’s second-largest economy grew by 6.1%, down from 2018’s 6.6%, already the lowest since 1990. Growth in the three months ending in December held steady at the previous quarter’s level of 6% over a year earlier. Business sentiment received a boost from Wednesday’s signing of a truce in the costly war over Beijing’s technology ambitions and trade surplus.
