COLOMBO, July 18 (Reuters) - Sri Lankan shares ended weaker on Monday, from their more than three-week closing high hit in the previous session, as investors turned cautious ahead of the government's policy statement next month.
The bourse touched a three-week high on Friday after investor sentiment was boosted with Sri Lanka raising $1.5 billion in its first sale of dual-tranche eurobonds last week, as over $5.5 billion in offers for the issue showed that global investors were bullish about prospects of the $82 billion economy.

The benchmark Colombo stock index in thin trade ended down 0.11 percent or 6.88 points at 6,415.81, slipping from its highest since June 21 hit on Friday. It gained 0.9 percent last week.

Prime Minister Ranil Wickremesinghe is expected to announce the country's economic policies in August, said new central bank chief Indrajith Coomaraswamy last week.
