BEIJING - Chinese labor unions will likely give more than 4 billion yuan ($637.84 million) in aid during New Year visits paid to needy workers, the All China Federation of Trade Unions (ACFTU) said Sunday.

Labor unions nationwide will deliver greetings and relief funds to migrant workers, temporary workers and workers who are in poverty because of illness before and during the upcoming Spring Festival holiday, the ACFTU said.

The funds will be provided to the poorest workers and those who have the most urgent needs, the ACFTU said.

ACFTU data indicates that China currently has 4.96 million needy working households, an increase of 40,000 from the end of 2011. Of the households, 839,000 are migrant worker households, according to ACFTU data.
