BEIJING -- China's current account stayed in a reasonable surplus range in 2018, official data showed Friday.

The country's current account registered a surplus of $49.1 billion last year thanks to robust surplus growth in the last quarter, according to the State Administration of Foreign Exchange (SAFE).

China's reserve assets grew 18.9 billion dollars last year, with an increase of 18.2 billion dollars in the forex reserve.

The non-reserve financial account posted a surplus of 60.2 billion dollars as direct investment reported a net inflow of 107.4 billion dollars, surging 62 percent year on year.

Cross-border capital flow is expected to be generally stable, and the international balance of payments will also maintain basic equilibrium, according to SAFE spokeswoman Wang Chunying.
