SINGAPORE - The People's Action Party (PAP) marked its 62nd anniversary on Monday (Nov 21) by pledging to continue to serve Singaporeans with humility and passion.

Although the journey towards SG100 will be challenging as global uncertainties have become more severe and dynamic, plans are in place to help Singaporeans seize opportunities, said the party's organising secretary Chan Chun Sing in a letter on the PAP's website.

"The external geopolitical shifts and our internal socio-economic challenges will require us to stay nimble to chart our course most carefully in the coming years," he said.

The issues that will impact Singapore include the deep divide in the United States, China's evolving socio-economic challenges and the European Union's future, as well as Singapore's ageing population and maturing economy.

Still, there is reason for optimism and there are bright spots in the economy, he added. "The PAP has put in place a comprehensive strategy to help all sectors of the economy and our workers."

Mr Chan, leader of the trades union movement and Minister in the Prime Minister's Office, highlighted the many ups and downs the nation had experienced since the 1960s.

They range from the pullout of British forces in the 60s, the oil crisis in the 70s, the global recession of the 80s, the Asian financial crisis in the 90s, and the subprime crisis of 2008.

These have made Singapore stronger, he said.

"The PAP government proactively stepped up its efforts, at every defining moment to protect the livelihood and improve the lives of all Singaporeans, because we cared," he added.

The party has been guided by the principles laid down by its founding leaders, he said. "The PAP will continue to serve Singaporeans with humility and passion. Singaporeans, young and old; the able and disabled have placed their trust in us and hope that we will do the best for them and their children. We have, and will continue to do so.

"We must continue to uphold our core values to have a multi-racial, meritocratic Singapore. That's our promise to all Singaporeans."
