The Umno supreme council member said he is more keen on promoting BN as a "product" rather than criticising Pakatan Rakyat, Soros, or human rights NGO Suaram.
"If we show the downside of other people's product, we can't control its quality whereas we can control (the quality of) our products.
"What if Soros whom we are condemning (now) comes up with a statement that suits us tomorrow or the day after?
"That's why I'm not too interested in attacking Soros or Suaram," Saifuddin (right) told Malaysiakini.
Former prime minister Dr Mahathir Mohamad had previously laid the blame for the 1997 Asian currency crisis squarely on Soros.
He returned to the spotlight of late when the mainstream media ran reports charging him with funding Suaram and Malaysiakini in a attempt to topple the government.
At the same time, Prime Minister Najib Abdul Razak reportedly had a secret meeting with Soros in New York last year.
Subang MP Sivarasa Rasiah had revealed this during debate with Perkasa information chief Ruslan Kassim, and this was confirmed by Malaysaiakini.
Commenting on the issue, Saifuddin said this revelation is proof that promoting the BN is better than condemning Pakatan Rakyat.
"That's why I said so. I know elections are around the corner and we should campaign to win the support of the people.
"However I'd prefer to talk about the values that BN can bring than condemning others.
"If it is true that Najib had met Soros, then we shall wait (and see) what really transpired in that meeting," he added.
