From the LA Times:
China is likely to employ a combination of incentives, arguments and mild scare tactics in coming weeks as it tries to persuade North Korea to resume negotiations aimed at ending its nuclear weapons program. But it won’t be easy to succeed, analysts say, given the complexities of dealing with the isolationist state, even for Pyongyang’s neighbor, fellow communist regime and closest ally.
Probably the greatest incentive China can offer North Korea is an enhanced aid package, possibly with South Korea’s help, essentially a sweetener to convince the Stalinist state to rejoin six-nation talks that also involve the United States, South Korea, Japan and Russia. Beijing has pledged as host of the talks to try to bring Pyongyang back to the table.
