WASHINGTON, June 30--State Department officials said today the Cuban rebels appeared to be attempting, by kidnapping United States citizens, to force the United States to impose a more complete curb on assistance to the Batista Government of Cuba.

The United States held up a shipment of Garand rifles to the Cuban Government at the end of March, and other shipments destined for the rebels have been confiscated before and since.

The State Department position stated April 3 was that the United States would weigh carefully any requests for authorization to ship arms to a troubled area such as Cuba.  But it did not impose a full embargo on arms shipments to Cuba.

The State Department disclosed that Park W. Wollam, United States Consul at Santiago de Cuba, reached a rebel camp yesterday and saw two of the men seized.

Mr. Wollam reported that the two men were well and said that eight other Americans and two Canadians being detained were also well.  Meanwhile in the Senate, Senator Styles Bridges, Republican of New Hampshire, said that the United States must expect such kidnapping of its citizens as long as it displayed weakness in international affairs.

The Senator related kidnapping of forty-four North Americans in Cuba and the detention of nine American airmen in East Germany.  Nine more American airmen are being held in the Soviet Union.  Communist Chine still holds four United States citizens.

Lincoln White, State Department press officer, said that efforts to obtain release of the kidnapped men were continuing.

According to other State Department officers, there were indications that the kidnappings were engineered by Raul Castro, brother of the rebel leader, Fidel Castro.  Raul Castro is considered more "extremist" than his brother and inclined to an anti-United States view.

The officials said that Raul may have staged the kidnappings in order to force his brother to take a stronger stand against what some of the rebels consider United States support of the Bastista regime.

Leaflets recently distributed by rebel sympathizers in Washington showed a picture of a Cuban Government aircraft being refueled by an American truck at Guantanamo Air Base.  According to the leaflet, this proved teh United States was helping the Batista regime.

State Department officials asserted, however, that teh plane shown was a Cuban Airlines aircraft and that no military plane had ever been refueled.
