Wang Chunying also told reporters during a briefing in Beijing that cross-border capital flows will remain stable in the second half of the year.
China posted a $33.7 billion current account deficit for the first three months of the year, with the regulator saying international payments were affected by the coronavirus outbreak.
Foreign investment in China's bond and stock markets has picked up sharply in recent months as the economy recovers from the health crisis, pushing equities into a bull market. But Wang said the impact of inflows into stocks has been acceptable so far, and the current account should remain within a reasonable range in the future.
