Cambodian Deputy Prime Minister and Defense Minister Tea Banh on Thursday warned main opposition against unlawful acts in its daily protests against Prime Minister Hun Sen's government.

"In the latest development, the opposition's protesters are demanding the legitimate Prime Minister (Hun Sen) of the government to step down, or to hold a re-election. This demand is out of date and their time has not come,"he told reporters after a conference.

He said the country has its own law, the opposition cannot do anything unlawfully to achieve its outlawed ambitious goal.

The opposition Cambodia National Rescue Party (CNRP) has launched a new round of daily protests in capital Phnom Penh since Sunday to demand Hun Sen to hold a snap election, or step down.

CNRP's leader Sam Rainsy has led thousands of protesters into the streets in the city while shouting in chorus "Hun Sen step down."

"If you are brave enough, allow a re-election, or step down," Sam Rainsy repeatedly shouted during those peaceful rallies.

Tea Banh said demonstrations were their rights, but they had to comply with the nation's constitution and law in order to avert any adverse impact on economic and social development.

"Wanting to follow neighboring Thailand is impossible. Here is Cambodia, not Thailand," he said, referring to Thailand where the anti-Thai government protest,led by former Democrat Member of Parliament Suthep Thaugsuban, captured key government buildings last month in an attempt to oust Prime Minister Yingluck Shinawatra .

Tea Banh said the ruling Cambodian People's Party still keeps its door open to negotiations with the CNRP.

Political dispute between the Hun Sen's ruling party and the Sam Rainsy's opposition party has persisted since the July's election results showed that the ruling party won a majority of vote with 68 parliamentary seats against 55 seats for the opposition.

The opposition refused to accept the outcome and boycotted parliament since then in order to call for an independent probe into the alleged irregularities during the poll, but the ruling party rejected the call, saying it was against the nation's constitution.

One of the protests in mid-September turned violent as protesters threw stones at police and the police retaliated with tear gas, smoke bombs, and water cannons. A protester was shot dead and several were wounded in the clashes.
