I don’t know if east Asia (which I assume is what you’re referring to) has an analog to rice pudding, but…

en.wikipedia.org/wiki/Rice_pudding

Rice pudding is a dish made from rice and milk, and commonly other ingredients such as sweeteners, spices, flavourings and sometimes eggs.

Variants are used for either desserts or dinners. When used as a dessert, it is commonly combined with a sweetener such as sugar. Such desserts are found on many continents, especially Asia, where rice is a staple. Some variants are thickened only with the rice starch, while others include eggs, making them a kind of custard.[1]

The article does mention a couple of similar east Asian dishes:

East Asia

Ba bao fan (Chinese) with glutinous rice, red bean paste, lard, sugar syrup, and eight kinds of fruits or nuts; traditionally eaten at the Chinese New Year

Put chai ko (Hong Kong) made with white or brown sugar, long-grain rice flour, red beans, and a little cornstarch. It can be commonly found as street food and has a gelatinous consistency.

Tarak-juk (Korea): juk (rice porridge) made with milk.

I mean, I can run down to my local 7-11 and get cups of the stuff 24/7.
