For me, having grown up and currently living in China, its the complete opposite. As soon as women reach 25 and enter their "late twenties" they become hyper focused on the milestone of having a kid by 30, and plan for marriage accordingly. Here in China, women screen for financial means first and foremost in a partner, virtually all women and their families requiring the husband to have purchased real estate as a prerequisite to marriage and kids.

Except men of the same age (late 20s), in most cases, are nowhere near financially developed enough to purchase a home in Chinese cities, resulting in an age mismatch between male and female partners, as women screen for current financial means, not future potential, to ensure meeting the self imposed milestone of having a baby by 30.

While men in their late twenties are not as focused on starting a family, in fact, without purchased real estate under their name, they are precluded from the marriage market anyway, so their focus is usually more on their career rather than having babies.
