Nepal will adopt its first full democratic charter Sunday, a historic step for a nation that has seen war, a palace massacre and devastating earthquakes since a campaign to create a modern state began more than 65 years ago.

President Ram Baran Yadav will formally promulgate the constitution, which is intended to unite the country, but it has already exacerbated divisions in some places, with 40 people killed in protests against it in recent weeks.

India and China, Nepal's powerful neighbors, are keen to see stability and to limit each other's influence in the poor Himalayan country sandwiched between them.
