BEIJING — China’s growth fell to its slowest pace in nearly three decades, officials disclosed on Monday, as a resurgence of trade tensions with the United States and lingering financial problems take an increasing toll on one of the world’s most vital economic engines.

Chinese officials said the economy grew 6.2 percent between April and June compared with a year earlier. While such economic growth would be the envy of most of the world, it represented the slowest pace in China since the beginning of modern quarterly record-keeping in 1992. That marks a significant slowdown from earlier this year, when growth came in at 6.4 percent, matching a 27-year low reached during the global financial crisis a decade ago.

Premier Li Keqiang set a target in March for economic growth to be between 6 and 6.5 percent this year. The figures on Monday fell within that range.

But much of the growth in the quarter may have taken place in April and early May, when public confidence was higher because of a tax cut in March and heavy infrastructure spending as spring began. Trade talks broke down on May 10 and President Trump raised tariffs sharply on Chinese goods, a step that damaged consumer confidence within China. Growth early in the quarter also would have taken place before the contentious government takeover of a bank in late May hurt financial confidence.
