China is imposing a ban on North Korean ships entering its ports. Chinese media quoted the foreign ministry as saying that Beijing was applying the terms of latest United Nations resolution. Robin Brant reports more from Shanghai.

United Nations approved further sanctions last week, placing even more stringent restrictions on North Korea's ability to trade. China hasn't always enforced those measures as tightly as others. It remains the prior state's only significant ally. But China's foreign minister said all North Korean ship will be now be barred from entering its ports. The People's Daily described Wang Yi's comments as a full implementation of the UN sanctions.

In Myanmar, the National League for Democracy which dominates parliament has put forward the names of two nominees to become vice presidents of the country. One of them should eventually be chosen as president. Htin Kyaw, a trusted aid of the party leader Aung San Suu Kyi, is one of the candidates. It's thought he'll get the job but as our reporter Jenna Fischer explains he'll act as a proxy for Ms Suu Kyi who is barred from standing.

Aung San Suu Kyi has made it pretty clear that whatever position she's put in, whoever she has to put in as president of this country, that she will still be the one in charge, she will lead this government, she will be making those decisions. So Htin Kyaw, when he becomes president of this country, he'll still have take orders from her.

The two contenders for the Democratic party's presidential nomination in the US, Bernie Sanders and Hillary Clinton, have argued fiercely over their records in their latest televised debate. They also clashed on their immigration policies as Laura Bicker reports from Washington.

The candidates faced tough questions on immigration. They both agreed they would not deport children or immigrants without criminal records and they both favor a path to citizenship. Hillary Clinton was also asked about polling which suggests voters think she is not trustworthy. She said it was obviously painful for her to hear. And she is not a natural politician like her husband or Barack Obama. But she hoped people could see she was fighting for them.
