New wording in the law requiring people to visit or keep in touch with their elderly parents or risk being sued came into force Monday, as China faces increasing difficulty in caring for its aging population.

The amended law does little to change the status quo, however, because elderly parents in China already have been suing their adult children for emotional support and the new wording does not specify how often people must visit or clarify penalties for those who do not.

It is primarily aimed at raising awareness of the issue, said one of the drafters, Xiao Jinming, a law professor at Shandong University. “It is mainly to stress the right of elderly people to ask for emotional support … we want to emphasize there is such a need,” he said.

China’s legislature amended the law in December following frequent reports of elderly parents neglected by their children. It says offspring of parents older than 60 should see that their daily, financial and spiritual needs are met.

The number of Chinese seniors is expected to skyrocket from the current 185 million to 487 million, or 35 percent of the population, by 2053, according to figures from the China National Committee On Aging.

The expanding ratio is due both an increase in life expectancy — from 41 to 73 over five decades — and by family planning policies that limit most urban families to a single child.
