As China has showed a slight decrease in population and meanwhile an increasing number of young couples show their willing to have the other baby, recently, a new policy has come into being that each family can have a second child, which is called two-child policy.
recently 前后两个逗号都是对的。前一个逗号表示在 as 时间从句之后的停顿（as 从句太长，无论在口语还是书面语，都需要停顿一下，分出从句和主句），第二个逗号，是后面句子的时间状语。一般而言，时间状语放在句首时，往往加逗号停顿。
