The Liberal Democratic Party has drafted a set of additional punitive steps against North Korea as the latest six-party talks on Pyongyang's nuclear programs ended Friday without progress, lawmakers said.

The proposal for further sanctions in four stages was compiled by a party task force for submission to the government early next year, they said.

Japan imposed unilateral sanctions immediately after North Korea launched missiles into the Sea of Japan on July 5 and imposed additional measures, including bans on trade and the entry of North Korean ships and people, after the Oct. 9 nuclear test.

The LDP task force, headed by House of Councilors member Ichita Yamamoto, aims to give the government additional diplomatic cards for drawing concessions from North Korea over the nuclear and abduction issues.

The proposal, submitted to LDP Policy Research Council Chairman Shoichi Nakagawa, includes calls for tougher financial screening, broader financial sanctions and further bans on trade and port calls.

The requirement for financial institutions to report overseas remittances of more than 300 million yen will be toughened for North Korea to include amounts of more than 10 million yen.

The government has already frozen the Japanese bank accounts of 15 organizations and one individual suspected of links to North Korea. The LDP's proposal calls for this to be expanded.

It also wants a total ban on exports in addition to the government's total ban on imports. It proposed extending the ban on port calls by North Korean ships to cover any ships that have stopped at North Korean ports.

The six-party talks in Beijing entered a recess Friday without progress after resuming earlier in the week following a 13-month suspension.
