SANTIAGO, March 18 (Reuters) - Chile's gross domestic product grew by just 0.1 percent in the fourth quarter from the prior period, and growth for all of 2015 reached 2.1 percent, the central bank said on Friday.
The quarter-on-quarter figure was below the 0.3 percent growth that economists in a Reuters poll had expected.
On an annual basis, fourth-quarter growth in the top copper exporter was 1.3 percent, compared with a 1.6 percent estimate.
The 2015 annual growth reading was slightly higher than the five-year low of 1.9 percent growth registered in 2014, but continued weakness in mining investments due to cooling demand in China and falling copper prices has held back a rebound.
The central bank said mining, fishing and the restaurant and hotel sector had a negative 2015, although other sectors were positive.
Copper makes up more than half of Chile's exports by value, but the country is also an important producer of paper, salmon, fruit and wine. (Reporting by Rosalba O'Brien; Editing by Lisa Von Ahn; Editing by David Goodman)
