BANGKOK (Reuters) - Shares in Thai construction contractors jumped more than 3 per cent on Monday on expectations that a new military government would speed up disbursements for infrastructure projects that have been put on hold during months of political unrest.

At 11.04am Singapore time, third-largest contractor Sino-Thai Engineering and Construction was up 3 per cent and second-ranked Ch Karnchang nearly 4 per cent.

The overall market was down 0.5 per cent.

Shares in Italian-Thai Development, the country's largest constuction firm, rose 0.5 per cent, even though the army has summoned its president, Premchai Karnasuta, to appear before it on Monday.
