had the same rulers/ruling party for decades

Alternatively (with apologies for playing a bit fast and loose in terms of President/Prime Minister/Secretary - political systems come in many shapes and sizes) and note that in some of these political party doesn't make much sense - when a military strongman stages a coup and holds power for a decade and a half, is there really a ruling political party?

    Japan-
    Liberal Democratic Party: 1955-1993, 1994-2009, 2012 to present

    Singapore-
    People's Action Party: 1959 to present
    Lee Kuan Yew: 1959 to 1990
    Goh Chok Tong: 1990 to 2004

    South Korea-
    Syngman Rhee: 1948 to 1960 (interestingly, exempted himself from an eight-year limit in 1954)
    Park Chung-hee: 1963 to 1979 (took power in military coup, assassinated)

    Taiwan-
    Chiang Kai-shek: 1950 to 1975
    Kuomintang Party: 1950 to 1996, had the advantage of being a single-party state until roughly late eighties

Definitely some decades in there.

That's goalpost motion, though. By that standard the Chinese policy change in the headline is a total nothingburger because the communist party has been in power since the revolution and will continue to be after Xi is dead.

Obviously, no: the headline is significant; east asian governments are subject to policy change and reform even within a single party rule; and this is a canard. There is a difference between indefinite rule by an abstract "party" and indefinite rule by an actual person. And China is crossing that gap.

That level of political discussion is beyond me. I'm just presenting some examples of East Asian countries that had the same ruler / ruling-party for decades.

What EliRivers described is exactly what I was referring to. And I don't think the "headline" is particular important btw.

How is removing hard limit on two terms "crossing that gap"? It'd be a much greater leap if Xi wants to rule indefinitely. Xi (and the communist party) wants stability, and he has to answer to what the people want to keep staying in power

I've lived in China, Singapore, and US for a long time. And I have to say Singapore government is apparently the most reasonable one out of the three. It most likely also have highest approval rate.

Even Singapore's PM was given a popular mandate via parliamentary elections. Singapore and the PAP has some aspects of authoritarianism, but it still believes deeply in the rule of law.

I would encourage further self-directed historical research if you honestly believe this to be the case.

Halimah Yacob is the President, not the Prime Minister, very different positions. Look up "Minister Mentor."

Lee Hsien Loong is LKY's son.
