Datuk Seri Najib Tun Razak has challenged his critics to give ideas for a more progressive and resilient nation instead of continuously finding fault with the Government.
The Prime Minister said he did not mind being criticised but did not like criticisms without solutions.
"It is easy to criticise, it is easy to pass comments in a negative way, but please ask yourself: 'What can I contribute in terms of ideas and solutions?'
"I don't mind criticisms, but when you ask the critics 'What do you have in mind?', they look at you blankly.
"They have no ideas," Najib, who is on a three-day visit to the city, said during a dinner with some 200 San Francisco-based Malaysians on Sunday.
Present were his wife Datin Seri Rosmah Mansor, Communication and Multimedia Minister Datuk Seri Ahmad Shabery Cheek and Johor Mentri Besar Datuk Seri Mohamed Khaled Nordin.
The Prime Minister said he introduced the 1Malaysia concept for all to have a sense of belonging and contribute to the nation.
He added that while the Government was doing its level best to achieve developed and high-income status by 2020, it does not help when fellow Malaysians go abroad and start rubbishing their own country.
Worse, he said, they start spinning untrue stories.
"There are individuals who go abroad and tell lies to other Malaysians, including claims we manipulated the general election by bringing in 40,000 Bangladeshis.
"Until today they have not been able to produce one bit of evidence.
"People were angry with us but the truth is we did not cheat. It was a fair and honest election and we prevailed despite the onslaught," he said.
Najib said social media was used to spread lies when it should be used in a constructive way for the betterment of society as well as for spreading knowledge and information.
"It can go viral. It is important for us to develop Malaysians who can think in critical and creative ways.
"As we move forward as a nation, we need our economy to increase our innovation and entrepreneurial skills - elements that bring our nation to the fore and be competitive.
"You are in the US not because you are less patriotic. I don't believe Malaysians who work or reside abroad are less patriotic.
"These are exciting times in Malaysia. I know not everything is rosy but by and large we are trying to do better and better. We are trying to improve," he said.
