Seoul -- A strike by South Korean truckers entered its third day Sunday, forcing the country's largest port to reduce its operations, officials said.

The Port of Busan cut its freight-loading level by more than 75 percent of normal, Yonhap reported Sunday.

Other ports had been forced to operate below 10 percent of capacity, the news agency reported.

The strike has also forced industry to slow product shipments. LG Electronics Inc., the world's fourth-largest mobile phone maker, for instance, said Saturday it was forced to cease product shipments from its factory in South Gyeongsang Province.

The truckers are calling on the government of President Lee Myung-bak to lower gasoline prices, and on their employers to raise fees.

"One hundred percent of our 13,000 union members are participating in the strike, and there many more non-unionized truckers participating," said Park Sang-hyun of the Korea Cargo Transport Workers' Union, the nationwide truck drivers' union.

Unionized truck drivers account for only 3 percent of the 337,000 truckers in the country, Yonhap said.
